| JMeter 5.6.x requires Java 8 or later for execution (Java 17 or later recommended). |
| <br></br> |
| <b>The next major release would require Java 17 or later.</b> |

| <!-- =================== 5.6.3 =================== --> |

| |
| <h3>General</h3> |
| <ul> |
| <li>Restored binary API compatibility with pre-5.6.2: restore public methods to non-static as they were before 5.6.2 <code>JavaSamplerContext.getJMeterVariables</code>, |
| <code>JavaSamplerContext.getJMeterProperties</code>, <code>BoundaryExtractor.extractAll</code>, |
| <code>AuthManager.setupCredentials</code>, <code>HttpRequestHdr.getMultipartConfig</code>, (regression since 5.6.2)</li> |
| </ul> |

| <!-- =================== Known bugs or issues related to JAVA Bugs =================== --> |
| |
| <ch_section>Known problems and workarounds</ch_section> |
| <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(…) 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> |
| |
| <li> |
| 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. |
| <source> |
| Warning: Nashorn engine is planned to be removed from a future JDK release |
| </source> |
| To silence these warnings, add <code>-Dnashorn.args=--no-deprecation-warning</code> to your Java arguments. |
| That can be achieved by setting the enviroment variable <code>JVM_ARGS</code> |
| <source> |
| export JVM_ARGS="-Dnashorn.args=--no-deprecation-warning" |
| </source> |
| </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_14_Release/rhino-engine-1.7.14.jar">rhino-engine-1.7.14.jar</a> into <code>$JMETER_HOME/lib/ext</code>.</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 (or later) and its dependencies and set the module path is outlined below: |
| <source> |
| 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 |
