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 constraintsif 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.securitySee 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_ARGSexport JVM_ARGS=”-Dnashorn.args=–no-deprecation-warning”
