[7u60] - Request for approval : 8017779, 8003253, 8003285, 8003895

[Seán Coffey]

Looking for approval for these test stabilization fixes.

These are backports from JDK 8. The 
java/nio/channels/AsynchronousChannelGroup/Unbounded.java changes came 
back smoothly with the exception of not making changes to 
ProblemList.txt. This test wasn't on the ProblemList for 7u.

For the java/net/Authenticator/B4769350.java port, code was a little 
different given that the refactoring exercise done in JDK 8 for 
HttpServer classes wasn't backported to JDK 7u (6354758) - cc'ing Chris 
with the hope he can give that a quick overview.

Tests have been run through JPRT without issues.
