Norman Maurer f8e158a39f [#3457] Proper fix for IllegalStateException caused by closed file descriptor / channel ... Motivation: During 6b941e9bdb I introduced a regression that could cause an IllegalStateException. A non-proper fix was commited as part of #3443. This commit add a proper fix. Modifications: Remove FileDescriptor.INVALID and add FileDescriptor.isOpen() as replacement. Once FileDescriptor.close() is called isOpen() will return false. Result: No more IllegalStateException caused by a close channel.		2015-03-01 19:36:31 +01:00
