Sets the native stack size for operating system threads.
You can use the
-verbose:sizes option to find out the values that the VM is currently using.
When a native method makes a call into the VM, the VM calculates whether the memory required for the call will exceed the
-Xmso value. If so, a
java/lang/StackOverflowError error is thrown.
Note: Java methods and native methods run on two different stacks and the VM handles switching between them for JNI calls. Each stack is sized using separate options; this option applies to the native stack only. For the Java stack option, see the link in the See also section.
See Using -X command-line options for more information about the
Default values vary by platform. See Default settings for the OpenJ9 VM.
