JVM halts without completing method will the local variable still remains in stack?

Local variables gets placed in stack when method is called and when JVM halts without completing the method, will the local variable still remain on the stack?

Example:

void Method() {
    int a=2;
    System.exit(0);
    Foo f=new Foo();
}

There is no stack after the process exits, so there are certainly no local variables left on it, or anything else either.

The Java-level stack will be gone, and the OS will free the memory. However, nothing is going to actually zero it out so the stack variables will remain in that sense.

When you restart the vm you will have fresh values and a fresh stack. Anything after a System.exit(0) won't be called.

No. After the System.exit(0) the system will clean-up the mess.
