> This page details the changes made in the current version only. Earlier changes are detailed in the History of Previous Changes.

> JMeter 5.6.x requires Java 8 or later for execution (Java 17 or later recommended). The next major release would require Java 11 or later.

> # Version 5.6.2

> Summary

> - Bug fixes

> Bug fixes

> ### General

> - Pull request #6042 - Issue #6041Fix compatibility with Maven's pom.xml parser by adding explicit versions for `com.google.auto.service:auto-service-annotations` (regression since 5.6)

> Thanks

> We thank all contributors mentioned in bug and improvement sections above:

> We also thank bug reporters who helped us improve JMeter.

> Apologies if we have omitted anyone else.

> Known problems and workarounds

> - The Once Only controller behaves correctly under a Thread Group or Loop Controller, but otherwise its behaviour is not consistent (or clearly specified).
> - 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 `0` (see Bug 55510 ).
> - Note that under some windows systems you may have this WARNING:

>       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.

>   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:

>       java.security.cert.CertificateException: Certificates does not conform to algorithm constraints

>   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+.
>   To allow you to perform your HTTPS request, you can downgrade the security of your Java installation by editing the Java `jdk.certpath.disabledAlgorithms` property. Remove the MD2 value or the constraint on size, depending on your case.
>   This property is in this file:

>       JAVA_HOME/jre/lib/security/java.security

>   See Bug 56357 for details.
> - 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 JDK-8065373 The fix is to use JDK8_u45 or later.
> - View Results Tree may fail to display some HTML code under HTML renderer, see Bug 54586 . This is due to a known Java bug which fails to parse "`px`" units in row/col attributes. See Bug JDK-8031109 The fix is to use JDK9 b65 or later.
> - JTable selection with keyboard (SHIFT + up/down) is totally unusable with Java 7 on Mac OSX. This is due to a known Java bug JDK-8025126 The fix is to use JDK 8 b132 or later.
> - Since Java 11 the JavaScript implementation Nashorn has been deprecated. Java will emit the following deprecation warnings, if you are using JavaScript based on Nashorn.

>       Warning: Nashorn engine is planned to be removed from a future JDK release

>   To silence these warnings, add `-Dnashorn.args=--no-deprecation-warning` to your Java arguments. That can be achieved by setting the enviroment variable `JVM_ARGS`

>       export JVM_ARGS="-Dnashorn.args=--no-deprecation-warning"

> - With Java 15 the JavaScript implementation Nashorn has been removed. To add back a JSR-223 compatible JavaScript engine you have two options:
>   Use Mozilla Rhino
>     Copy rhino-engine-1.7.14.jar into `$JMETER_HOME/lib/ext`.
>   Use OpenJDK Nashorn
>     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 (or later) and its dependencies and set the module path is outlined below:

>         mkdir lib/modules
>         pushd lib/modules
>         wget https://repo1.maven.org/maven2/org/openjdk/nashorn/nashorn-core/15.3/nashorn-core-15.3.jar
>         wget https://repo1.maven.org/maven2/org/ow2/asm/asm/9.5/asm-9.5.jar
>         wget https://repo1.maven.org/maven2/org/ow2/asm/asm-commons/9.5/asm-commons-9.5.jar
>         wget https://repo1.maven.org/maven2/org/ow2/asm/asm-util/9.5/asm-util-9.5.jar
>         wget https://repo1.maven.org/maven2/org/ow2/asm/asm-tree/9.5/asm-tree-9.5.jar
>         wget https://repo1.maven.org/maven2/org/ow2/asm/asm-analysis/9.5/asm-analysis-9.5.jar
>         popd
>         export JVM_ARGS="--module-path $PWD/lib/modules"
>         ./bin/jmeter
