Yeah, I was merely guessing, but it might surely be timing.

Happy to help I guess ;-). Issue added at HARMONY-6105. Also, from my
point of view, HARMONY-5924 can now be close.

Thanks.  I'll follow up HARMONY-5924 after the next snapshot or milestone
is available.

I should have said four bugs not three since I think I also spotted a
Sun bug too.  I notice that when I ran the test case on Sun, the strace
happened to contain:

  getsockname(0, 0x41586460, [103079215132]) = -1 ENOTSOCK (Socket operation
  on non-socket)

which really doesn't make much sense.

I'm not planning to report it. ;-)

Thanks again.
