Motivation SslHandler's handlerRemoved() is supposed to release the SSLEngine (which it does) but there is no Test for it to make sure it really happens and doesn't unexpectedly change in the future. Modifications Add a Unit Test that makes sure that SslHandler releases the SSLEngine when the Channel gets closed. Result Assurance that SslHandler will not leak (ReferenceCounted) SSLEngines.
