Note that there is a <a href= "http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6396599 " > bug in Java</a>
on some Linux systems that manifests itself as the following error when running the test cases or JMeter itself:
2012-09-12 08:32:27 +08:00
<pre >
[java] WARNING: Couldn't flush user prefs:
java.util.prefs.BackingStoreException:
java.lang.IllegalArgumentException: Not supported: indent-number
</pre>
2013-07-10 17:43:05 +08:00
This does not affect JMeter operation. This issue is fixed since Java 7b05.
</li>
2013-07-22 07:52:08 +08:00
2014-10-31 22:25:12 +08:00
<li >
Note that under some windows systems you may have this WARNING:
<pre >
java.util.prefs.WindowsPreferences
WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0
x80000002. Windows RegCreateKeyEx(...) 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>
2013-07-22 07:52:08 +08:00
<li >
2013-07-23 17:14:57 +08:00
With Java 1.6 and Gnome 3 on Linux systems, the JMeter menu may not work correctly (shift between mouse's click and the menu).
2014-12-06 01:29:15 +08:00
This is a known Java bug (see <bugzilla > 54477</bugzilla> ).
2013-07-22 07:52:08 +08:00
A workaround is to use a Java 7 runtime (OpenJDK or Oracle JDK).
</li>
2013-10-13 16:46:12 +08:00
<li >
With Oracle Java 7 and Mac Book Pro Retina Display, the JMeter GUI may look blurry.
This is a known Java bug, see Bug <a href= "http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8000629" > JDK-8000629</a> .
A workaround is to use a Java 7 update 40 runtime which fixes this issue.
</li>
2014-08-02 17:23:36 +08:00
2014-10-20 00:29:28 +08:00
<li >
You may encounter the following error: <i > java.security.cert.CertificateException: Certificates does not conform to algorithm constraints</i>
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 7 version u16 (MD2) and version u40 (Certificate size lower than 1024 bits), and Java 8 too.
<br > </br>
To allow you to perform your HTTPS request, you can downgrade the security of your Java installation by editing
the Java <b > jdk.certpath.disabledAlgorithms</b> property. Remove the MD2 value or the constraint on size, depending on your case.
<br > </br>
This property is in this file:
<pre > JAVA_HOME/jre/lib/security/java.security</pre>
See <bugzilla > 56357</bugzilla> for details.
