Review request for test bug 8015765: java/nio/channels/ServerSocketChannel/AdaptServerSocket.java

[Eric Wang]

Hi,

Please help to review the fix below for the bug 
https://jbs.oracle.com/bugs/browse/JDK-8015765.
http://cr.openjdk.java.net/~ewang/8015765/webrev.00/

As the test is depended on thread schedule, it may fail 
intermittently.The fix is to adjust thread priority, and increase thread 
sleep duration, to make it more stable.

Thanks,
Eric
