 <!--  =================== 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 <code>JEditorPane.setText()</code> or <code>JTextArea.setText()</code> 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 <code>md2WithRSAEncryption</code>) 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.
</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>
</ul>
