Description of problem:
Having started EAP 7.1.0.DR3, and trying to discover it with JON it fails with NPE [1]

Version-Release number of selected component (if applicable): JON 3.3.5 + jon-plugin-pack-eap-3.3.0.GA-update-04.zip 


How reproducible: always


Steps to Reproduce:
1. start EAP 7.1.0.DR3 in standalone mode
2. run discovery from jon agent, you will see that AS7 plugin found some matching processes, still the full discovery failed with [1] (and in JON server UI the server isn't visible between discovered resources)


Actual results:
EAP 7.1.x server is not discovered


Expected results:
EAP 7.1.x server is discovered.
