Just FYI.

The intermittent failures look like similar to some anti-free-port using 
issues.  In the current testing environment, for the InheritHandle test 
case, this anti-free-port using issue may looks like:

1. InheritHandle creates a server socket on a free port, and gets the 
port (PORT-A). (line 60-61)
2. InheritHandle close the server socket. (line 87)
3. Another test (TEST-B) creates a server socket on a free port. PORT-A 
may be used by the TEST-B.
4. InheritHandle create new server socket on PORT-A (line 88), it is 
expected to fail as PORT-A has been used by TEST-B.

The InheritHandle.java may run into intermittent failure unless it is 
run single alone.
