This option controls whether the VM captures the command line in the environment variable OPENJ9_JAVA_COMMAND_LINE. If enabled, the variable is set by the VM after it starts. Using this variable, you can find the command-line parameters set when the VM started. It applies not just to launchers (e.g. java) that are included in a JDK, but to any application that uses JNI_CreateJavaVM().


Setting Effect Default on z/OS Default on other platforms
-XX:+OpenJ9CommandLineEnv Enable yes
-XX:-OpenJ9CommandLineEnv Disable yes

This option is currently disabled by default on z/OS® because it might cause the VM to crash.
