<p>
JMeter now requires Java 8. Ensure you use the most up to date version.
</p>
<p>
JMeter logging has been migrated to SLF4J and Log4j 2.
This affects configuration and 3<sup>rd</sup> party plugins, see below <b>"Logging changes"</b>.
</p>
<ch_title>Core improvements</ch_title>
<ul>
<li>JMeter now provides a new BackendListener implementation that interfaces InfluxDB.
<figure width="813" height="407" image="changes/3.2/backend_influxdb.png"></figure>
This implementation sends data using Asynchronous HTTP calls to InfluxDB through its <a href="https://docs.influxdata.com/influxdb/v1.2/guides/writing_data/">HTTP API</a>
and give you the following graphs with annotations:
<figure width="934" height="399" image="backend_listener_influxdb_graph.png"></figure>
</li>
<li>DNS Cache Manager now has a table to allow static host resolution.
<figure width="803" height="561" image="changes/3.2/dns_cache_manager_static_hosts.png"></figure>
</li>
<li>JMS Publisher and Subscriber now allow reconnection on error with pause.
<figure width="852" height="738" image="changes/3.2/jms_publisher_reconnect.png"></figure>
<figure width="716" height="538" image="changes/3.2/jms_subscriber_reconnect_pause.png"></figure>
</li>
<li>Variables in JMS Publisher are now supported for all types of messages. Add the encoding type of the file to parse its content</li>
<figure width="750" height="743" image="changes/3.2/jms_subscriber_content_encoding.png"></figure>
<li>XPath Extractor now allows extraction randomly, by index or for all matches.
<figure width="823" height="348" image="changes/3.2/xpath_extractor_matchno.png"></figure>
</li>
<li>Response Assertion now allows to work on Request Header, provides a "OR" combination and has a better cell renderer
<figure width="1053" height="329" image="changes/3.2/response_assertion.png"></figure>
</li>
<li>JMeter now uses Oracle Nashorn Javascript engine instead of Rhino. This provides a faster execution of Javascript.</li>
<li>HTTP HC4 Implementation now provides preemptive Basic Auth enabled by default</li>
<li>Embedded resources download in CSS has been improved to avoid useless repetitive parsing to find the resources</li>
<li>An important work on code quality and code coverage with tests has been done since Sonar has been setup on the project.
You can see Sonar report <a href="https://builds.apache.org/analysis/overview?id=12927" >here</a>.
</li>
</ul>
<ch_title>UX improvements</ch_title>
<ul>
<li>When running a Test, GUI is now more responsive and less impacting on memory usage thanks to a limitation on the number of Sample Results
listeners hold and a rework of the way GUI is updated</li>
<li>HTTP Request GUI has been simplified and provides more place for parameters and body.
<figure width="848" height="475" image="changes/3.2/http_request.png"></figure>
</li>
<li>HTTP(S) Test Script Recorder has been simplified and clarified.
<figure width="1023" height="494" image="changes/3.2/http_recorder_1.png"></figure>
<figure width="1021" height="711" image="changes/3.2/http_recorder_2.png"></figure>
</li>
<li>A <code>replace</code> feature has been added to Search feature to allow replacement in some elements.
<figure width="459" height="196" image="changes/3.2/search_replace.png"></figure>
</li>
<li>View Results Tree now provides a more up to date Browser renderer which requires JavaFX.</li>
<li>You can now add through a contextual menu think times, this will add think times between samplers and Transaction Controllers
of selected node.
<figure width="326" height="430" image="changes/3.2/menu_add_think_times.png"></figure>
</li>
<li>You can now apply a naming policy to children of a Transaction Controller. A default policy exists but you can implement your own
through <code><a href="./api/org/apache/jmeter/gui/action/TreeNodeNamingPolicy.html" >org.apache.jmeter.gui.action.TreeNodeNamingPolicy</a></code>
and configuring property <code>naming_policy.impl</code>
<figure width="327" height="518" image="changes/3.2/menu_apply_naming_policy.png"></figure>
</li>
<li>Sorting per column has been added to View Results in Table, Summary Report, Aggregate Report and Aggregate Graph elements.
<figure width="1065" height="369" image="changes/3.2/sorting.png"></figure>
</li>
</ul>
<ch_title>Report/Dashboard improvements</ch_title>
<ul>
<li>
Statistics have been reorganized to clarify report:
<figure width="1548" height="366" image="dashboard/report_statistics.png"></figure>
</li>
<li>
It is now possible to customize APDEX thresholds per transaction based on regular expression or sample name.
The below example will apply different thresholds for samples sample(\\d+), sampleA and scenarioB
than default ones (500 and 1500 for satisfied and tolerated thresholds) declared:
<source>
jmeter.reportgenerator.apdex_satisfied_threshold=500
jmeter.reportgenerator.apdex_tolerated_threshold=1500
jmeter.reportgenerator.apdex_per_transaction=sample(\\d+):1000|2000;\
sampleA:3000|4000;\
scenarioB:5000|6000
</source>
</li>
</ul>
<ch_title>Documentation improvements</ch_title>
<ul>
<li>PDF Documentations have been migrated and updated to HTML user manual</li>
</ul>
<!-- =================== Incompatible changes =================== -->
<ch_section>Incompatible changes</ch_section>
<ul>
<li>JMeter requires now at least a Java 8 version to run.</li>
<li>JMeter logging has been migrated to SLF4J and Log4j 2, this involves changes in the way configuration is done. JMeter now relies on standard
<a href="https://logging.apache.org/log4j/2.x/manual/configuration.html">Log4j 2 configuration</a> in file <code>log4j2.xml</code>
See <code>Logging changes</code> section below for further details.
</li>
<li>The following jars have been removed after migration from LogKit to SLF4J (see <bugzilla>60589</bugzilla>):
<ul>
<li>ApacheJMeter_slf4j_logkit.jar</li>
<li>avalon-framework-4.1.4.jar</li>
<li>avalon-framework-4.1.4.jar</li>
<li>commons-logging-1.2.jar</li>
<li>excalibur-logger-1.1.jar</li>
<li>logkit-2.0.jar</li>
</ul>
</li>
<li>The <code>commons-httpclient-3.1.jar</code> has been removed after drop of HC3.1 support(see <bugzilla>60727</bugzilla>)</li>
<li>JMeter now sets through <code>-Djava.security.egd=file:/dev/urandom</code> the algorithm for secure random</li>
<li>Process Sampler now returns error code 500 when an error occurs. It previously returned an empty value.</li>
<li>In <code>org.apache.jmeter.protocol.http.sampler.HTTPHCAbstractImpl</code> two protected static fields (<code>localhost</code> and <code>nonProxyHostSuffixSize</code>) have been renamed to (<code>LOCALHOST</code> and <code>NON_PROXY_HOST_SUFFIX_SIZE</code>)
to follow static fields naming convention</li>
<li>JMeter now uses by default Oracle Nashorn engine instead of Mozilla Rhino for better performances. This should not have an impact unless
you use some advanced features. You can revert back to Rhino by settings property <code>javascript.use_rhino=true</code>.
You can read this <a href="https://wiki.openjdk.java.net/display/Nashorn/Rhino+Migration+Guide">migration guide</a> for more details on Nashorn. See <bugzilla>60672</bugzilla></li>
<li><bug>60729</bug>The Random Variable Config Element now allows minimum==maximum. Previous versions logged an error when minimum==maximum and did not set the configured variable.</li>
<li><bug>60730</bug>The JSON PostProcessor now sets the <code>_ALL</code> variable (assuming <code>Compute concatenation var</code> was checked)
even if the JSON path matches only once. Previous versions did not set the <code>_ALL</code> variable in this case.</li>
</ul>
<h3>Removed elements or functions</h3>
<ul>
<li>SOAP/XML-RPC Request has been removed as part of <bugzilla>60727</bugzilla>. Use HTTP Request element as a replacement.
See <a href="./build-ws-test-plan.html" >Building a WebService Test Plan</a></li>
<li><bug>60423</bug>Drop Monitor Results listener </li>
<li>Drop deprecated class <code>org.apache.jmeter.protocol.system.NativeCommand</code></li>
<li>Drop deprecated class <code>org.apache.jmeter.protocol.http.config.gui.MultipartUrlConfigGui</code></li>
<li>Drop deprecated class <code>org.apache.jmeter.testelement.TestListener</code></li>
<li>Drop deprecated class <code>org.apache.jmeter.reporters.FileReporter</code></li>
<li>Drop deprecated class <code>org.apache.jmeter.protocol.http.modifier.UserSequence</code></li>
<li>Drop deprecated class <code>org.apache.jmeter.protocol.http.parser.HTMLParseError</code></li>
<li>Drop unused methods <code>org.apache.jmeter.protocol.http.control.HeaderManager#getSOAPHeader</code>
and <code>org.apache.jmeter.protocol.http.control.HeaderManager#setSOAPHeader(Object)</code>
</li>
<li><code>org.apache.jmeter.protocol.http.util.Base64Encode</code> has been deprecated, you can use <code>java.util.Base64</code> as a replacement</li>
</ul>
<h3>Logging changes</h3>
<p>
JMeter logging has been migrated to SLF4J and Log4j 2.
This affects logging configuration and 3<sup>rd</sup> party plugins (if they use JMeter logging).
The following sections describe what changes need to be made.
</p>
<h4>Setting the logging level and log file</h4>
<p>
The default logging level can be changed on the command-line using the <code>-L</code> parameter.
Likewise the <code>-l</code> parameter can be used to change the name of the log file.
However the <code>log_level</code> properties no longer work.
</p>
<p>
The default logging levels and file name are defined in the <code>log4j2.xml</code> configuration file
in the launch directory (usually <code>JMETER_HOME/bin</code>)
</p>
<p>
<note>If you need to change the level programmatically from Groovy code or Beanshell, you need to do the following:
<source>
import org.apache.logging.log4j.core.config.Configurator;
&vellip;
final String loggerName = te.getClass().getName(); // te being a JMeter class
Configurator.setAllLevels(loggerName, Level.DEBUG);
</source>
</note>
</p>
<h4>Changes to 3<sup>rd</sup> party plugin logging</h4>
<p>
<note>3rd party plugins should migrate their logging code from logkit to slf4j. This is fairly easy and can be done by replacing:
<source>
import org.apache.jorphan.logging.LoggingManager;
import org.apache.log.Logger;
&vellip;
private static final Logger log = LoggingManager.getLoggerForClass();
</source>
By:
<source>
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
&vellip;
private static final Logger log = LoggerFactory.getLogger(YourClassName.class);
</source>
</note>
</p>

<!-- =================== Known bugs or issues related to JAVA Bugs =================== -->
<ch_section>Known problems and workarounds</ch_section>
<ul>
<li>View Results Tree may freeze rendering large response particularly if this response has no spaces, see <bugzilla>60816</bugzilla>.
This is due to an identified Java Bug <a href="https://bugs.openjdk.java.net/browse/JDK-8172336">UI stuck when calling JEditorPane.setText() or JTextArea.setText() with long text without space</a>.
</li>
</ul>
<ul>
<li>The Once Only controller behaves correctly under a Thread Group or Loop Controller,
but otherwise its behaviour is not consistent (or clearly specified).</li>
<li>
The numbers that appear to the left of the green box are the number of active threads / total number of threads,
the total number of threads only applies to a locally run test, otherwise it will show <code>0</code> (see <bugzilla>55510</bugzilla>).
</li>
<li>
Note that under some windows systems you may have this WARNING:
<source>
java.util.prefs.WindowsPreferences
WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0
x80000002. Windows RegCreateKeyEx(&hellip;) returned error code 5.
</source>
The fix is to run JMeter as Administrator, it will create the registry key for you, then you can restart JMeter as a normal user and you won't have the warning anymore.
</li>
<li>
You may encounter the following error:
<source>java.security.cert.CertificateException: Certificates does not conform to algorithm constraints</source>
if you run a HTTPS request on a web site with a SSL certificate (itself or one of SSL certificates in its chain of trust) with a signature
algorithm using MD2 (like md2WithRSAEncryption) or with a SSL certificate with a size lower than 1024 bits.
This error is related to increased security in Java 8+.
<br></br>
To allow you to perform your HTTPS request, you can downgrade the security of your Java installation by editing
the Java <code>jdk.certpath.disabledAlgorithms</code> property. Remove the MD2 value or the constraint on size, depending on your case.
<br></br>
This property is in this file:
<source>JAVA_HOME/jre/lib/security/java.security</source>
See <bugzilla>56357</bugzilla> for details.
</li>
<li>
Under Mac OSX Aggregate Graph will show wrong values due to mirroring effect on numbers.
This is due to a known Java bug, see Bug <a href="https://bugs.openjdk.java.net/browse/JDK-8065373" >JDK-8065373</a>
The fix is to use JDK8_u45 or later.
</li>
<li>
View Results Tree may fail to display some HTML code under HTML renderer, see <bugzilla>54586</bugzilla>.
This is due to a known Java bug which fails to parse "<code>px</code>" units in row/col attributes.
See Bug <a href="https://bugs.openjdk.java.net/browse/JDK-8031109" >JDK-8031109</a>
The fix is to use JDK9 b65 or later (but be aware that Java 9 is not certified yet for JMeter).
</li>
<li>
JTable selection with keyboard (<keycombo><keysym>SHIFT</keysym><keysym>up/down</keysym></keycombo>) is totally unusable with JAVA 7 on Mac OSX.
This is due to a known Java bug <a href="https://bugs.openjdk.java.net/browse/JDK-8025126" >JDK-8025126</a>
The fix is to use JDK 8 b132 or later.
</li>
