Trivial Description
We have a few tests that look for expected exceptions by manually catching and explicitly failing in case no exception happens.
Places that need to be fixed can be found by running:
$> grep -rie "[^n]expected *exception" `find . -name test -path '*/src/*' -type d | xargs`
(there are some false positives, e.g. TestIPv6NIOServerSocketChannel)
We should clean these up to use JUnit's expected arg to the Test annotation.
