Description Rafael Soares (Tuelho) 2011-06-03 13:41:42 UTC

Description of problem:
Some times you want to know what size being occupied by JVM threads allocated at the moment. This is an important metric to tuning the size of Java thread stack (using '-Xss' param on JVM). The Default stack size varies depending on Arch/OS used as platform. As the stack size of java threads are allocated outside of HEAP space, this metric could influence on accurately JVM tuning for a given platform.
