Major Description
ARTEMIS-3117 introduced code in 2.18.0 to invoke OpenSSLContextFactoryProvider.getOpenSSLContextFactory().clearSslContexts(); during stop of RemotingServiceImpl. See below for whole stacktrace.
This throws a NullPointerException for us running inside Karaf on stop due to the OpenSSLContextFactory being null at that point in time.
ARTEMIS-2791 was somewhat similar to this.
Requesting to not fail on the OpenSSLContextFactory being null during stop.
