Description

ServerSocketChannelTest will hang in 4 tests when run on platforms that have small socket buffers, such as z/OS. The tests are trying to send large amounts of data, so if the read or write cannot complete before the corresponding write or read takes place then the I/O will block from returning. I think this can only be fixed by having using threads in the testcase.

Minor change to SocketChannelTest.testCFII_StatusAfterFinish to remove output to stderr and fail if the expected exception wasn't thrown.
