I ran into this same problem. I too posted a note to the mailing list
but I did not hear back from anyone. The really odd part was that it
only seemed to happen when running with native threads. If I ran the
green threads version it worked just fine. Another strange thing that
seemed to happen with that native threads version is that reading
from System.in did not work when java was invoked from a shell script.
