Subject Re: [drlvm][threading] Some smoke tests started to hang this week on linux x86
Date Thu, 29 Mar 2007 15:51:44 GMT
HARMONY-3495 shows that gc.NPE fails in the JVM shutdown stage. Do you
think that all other tests fail in the same situation? Can you
explain, what makes you think that all these tests fail for the same
reason?

Thanks,
Peter.
