References remain on Thread stack

References remain on Thread stack

Suppose I have daemon Runnable whose run() looks like this:


public void run()
{
	while( !_stop )
      {
          waitForSomeConditionToBecomeTrue();
          doSomeWork();
      }
}

Now, in the doSomeWork() method local variables are created. The behavior
that I see is that between iterations of the while loop, these variables are
never GCed. The profiler I am using (OptimizeIt) indicates that these
local variables remain on the thread's stack. This is a concern to me
since these variables potentially occupy a lot of memory and there can be
long intervals of time between the while() iterations.

Is there a way to purge the thread's stack of references? Is this the
officially correct behavior of the GC?
