ARTEMIS-1804 don't call deprecated SslHandler#close() to avoid NPE in Netty
The stacktrace of the exception involves a deprecated method. For some
reason, using the recommended alternative does not produce the exception...
Could this PR be step in the right direction?
The Netty exception appears when OpenWire client which is using SSL
disconnects:
