Memory leak in java.lang.Thread ?

[Archie Cobbs]

Hi,

I'm trying to verify a memory leak in Classpath but since my VM has
some modifications I thought I'd quickly ask the list to try this test.

What happens when you run this program:

    public class ThreadLeak {
        public static void main(String[] args) {
            while (true)
                new Thread();
        }
    }

I get an OutOfMemoryError. This is because new threads are added
to their ThreadGroups in the Thread() constructor rather than when
the thread is actually started. Therefore, even if they are never
started they remain referenced an unable to be garbage collected.

If it's not just me then I'll file a bug and propose a patch.

Thanks,
-Archie
