Description

I am getting reports of problems loading the wildfly/openSSL binding even on a build which should have HADOOP-16405 on. I'm not sure that really is the case, but given that we have had problems here which surface aa NPEs, and we may end up having other linkage problems in future -I think we should catch all exceptions raised trying to instantiate the wildfly SSL bindings and fall back to the JVM.

I do want to log@warn here, because it is a sign of a problem. A full stack can come in at debug
