I need to check if some option that can be passed to JVM is explicitly set or has its default value.
To be more specific:
I need to create one specific thread with higher native stack size than the default one, but in case the user wants to take care of such things by himself by specifying the -Xss
option I want to create all threads with default stack size (which will be specified by user in -Xss option).
I've checked classes like java.lang.System
and java.lang.Runtime
, but these aren't giving me any useful information about VM arguments.
Is there any way to get the information I need?
At startup pass this -Dname=value
and then in your code you should use
value=System.getProperty("name");
to get that value
