The splash screen is now application-modal rather than system-modal, so it does not block other
applications when JMeter is starting up.</p>

<ul>
<li>Remove LogKit logger functionality from some classes. This was intended to completely remove
<span class="code">LoggingManager</span> class (it has been deprecated since JMeter 3.2), but as jmeter-plugins
depended on it, <span class="code">LoggingManager</span> and our <span class="code">LogKit</span>-adapter will remain for
this version (but is still deprecated).</li>

<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">

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.

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:

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.

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.

Since Java 11 the JavaScript implementation <a href="https://openjdk.java.net/jeps/335">Nashorn has been deprecated</a>.
Java will emit the following deprecation warnings, if you are using JavaScript based on Nashorn.
<pre class="source">
Warning: Nashorn engine is planned to be removed from a future JDK release
</pre>
To silence these warnings, add <span class="code">-Dnashorn.args=--no-deprecation-warning</span> to your Java arguments.
That can be achieved by setting the enviroment variable <span class="code">JVM_ARGS</span>
<pre class="source">
export JVM_ARGS="-Dnashorn.args=--no-deprecation-warning"
</pre>
</li>
<li>
With Java 15 the JavaScript implementation <a href="https://openjdk.java.net/jeps/372">Nashorn has been removed</a>. To add back a JSR-223 compatible JavaScript engine you have two options:
<dl>
<dt>Use Mozilla Rhino</dt>
<dd>Copy <a href="https://github.com/mozilla/rhino/releases/download/Rhino1_7_13_Release/rhino-engine-1.7.13.jar">rhino-engine-1.7.13.jar</a> into <span class="code">$JMETER_HOME/lib/ext</span>.</dd>
<dt>Use OpenJDK Nashorn</dt>
<dd>
The OpenJDK Nashorn implementation comes as a module. To use it, you will have to download it and add it to the module path. A hacky way to download the version 15.0 and its dependencies and set the module path is outlined below:
<pre class="source">
mkdir lib/modules
pushd lib/modules
wget https://repo1.maven.org/maven2/org/openjdk/nashorn/nashorn-core/15.0/nashorn-core-15.0.jar
wget https://repo1.maven.org/maven2/org/ow2/asm/asm/9.0/asm-9.0.jar
