The following command can be used to define the code heap size for the non-method compiled code:
-XX:NonMethodCodeCodeHeapSize
The following command can be used to define the code heap size for the profiled compiled methods:
-XX:ProfiledCodeHeapSize
The following command can be used to define the code heap size for the non-profiled compiled methods:
-XX:NonProfiledCodeHeapSize
