<h2 class="ch_section" id="Incompatible changes">Incompatible changes</h2>
<ul>
<li>
<span class="code">Start time</span> and <span class="code">End date</span> of Thread Group have been removed, see <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=61549">
Bug
61549</a>
</li>
<li>In distributed testing, mode <span class="code">Hold</span> has been removed. Use alternative and more efficient modes</li>
<li>For 3<sup>rd</sup> party plugins, the following method in <span class="code">org.apache.jmeter.gui.tree.JMeterTreeNode</span> has been dropped for migration to Java 9 (<a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=61529">
Bug
61529</a>)
<pre class="source">public Enumeration&lt;JMeterTreeNode&gt; children()</pre>
</li>
<li>
<span class="code">tearDown Thread Group</span> will now run on stop and shutdown of a test by default. If you don't want this behaviour,
uncheck <span class="code">Run tearDown Thread Groups after shutdown of main threads</span> on <span class="code">Test Plan</span> element, see <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=61656">
Bug
61656</a>
</li>
<li>Properties <span class="code">sampleresult.getbytes.headers_size</span> and <span class="code">sampleresult.getbytes.body_real_size</span> have been dropped, see <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=61587">
Bug
61587</a>
</li>
<li>JMeter will now save your test plan whenever you run it. This behaviour can be controlled by property <span class="code">save_automatically_before_run</span>, see <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=61731">
Bug
61731</a>
</li>
<li>Workbench element has been dropped, you now directly add <span class="code">Non Test Element</span> as children of Test Plan. When loading a Test Plan that contains the element
JMeter will move the <span class="code">Mirror Server</span>, <span class="code">Property Display</span> and HTTP(s) <span class="code">Test Script Recorder</span> elements as direct children of Test Plan. For
any other element, it will create a <span class="code">Test Fragment</span> element called <span class="code">Workbench Test Fragment and move the elements in it</span>.</li>
<li>Following classes have been dropped (<span class="code">org.apache.jmeter.functions.util.ArgumentEncoder</span>, <span class="code">org.apache.jmeter.functions.util.ArgumentDecoder</span>), see <a href="https://github.com/apache/jmeter/pull/335">
Pull request #335</a>
</li>
<li>In JMS Point-to-Point sampler, setting timeout to 0 will now mean infinite timeout while previously it would be switched to 2000 ms, see <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=61829">
Bug
61829</a>
</li>
<li>When Assertions are at different scopes, they are executed starting with the most OUTER one to the most INNER one. See <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=61846">
Bug
61846</a>
</li>
<li>JMeter now starts by default using English locale. This change is due to missing translations in many supported languages.
You can change locale by modifying in jmeter and jmeter.bat (or preferably setenv.sh/setenv.bat) the <span class="code">JVM_ARGS</span> system property values.
We'd also be very grateful if you can contribute translations in supported languages.
</li>
<li>SwitchController now trims by default the content of switch to avoid issue related to unwanted spaces. See <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=61771">
Bug
61771</a>
</li>
<li>JMeter JVM heap settings have changed from <span class="code">-Xms512m -Xmx512m</span> to <span class="code">-Xms1g -Xmx1g</span>

<li>View Results Tree may freeze rendering large response particularly if this response has no spaces, see <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=60816">
Bug
60816</a>.
This is due to an identified Java Bug <a href="https://bugs.openjdk.java.net/browse/JDK-8172336">UI stuck when calling <span class="code">JEditorPane.setText()</span> or <span class="code">JTextArea.setText()</span> 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 <span class="code">0</span> (see <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=55510">
Bug
55510</a>).
</li>
<li>
Note that under some windows systems you may have this WARNING:
<pre class="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.
</pre>
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:
<pre class="source">java.security.cert.CertificateException: Certificates does not conform to algorithm constraints</pre>
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 <span class="code">md2WithRSAEncryption</span>) or with a SSL certificate with a size lower than 1024 bits.
This error is related to increased security in Java 8+.
<br>
To allow you to perform your HTTPS request, you can downgrade the security of your Java installation by editing
the Java <span class="code">jdk.certpath.disabledAlgorithms</span> property. Remove the MD2 value or the constraint on size, depending on your case.
<br>
This property is in this file:
<pre class="source">JAVA_HOME/jre/lib/security/java.security</pre>
See <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=56357">

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.

View Results Tree may fail to display some HTML code under HTML renderer, see <a href="https://bz.apache.org/bugzilla/show_bug.cgi?id=54586">
Bug
54586</a>.
This is due to a known Java bug which fails to parse "<span class="code">px</span>" 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.

<li>
JTable selection with keyboard (<span class="keycombo"><span class="keysym">SHIFT</span>&nbsp;+&nbsp;<span class="keysym">up/down</span></span>) 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.
