Part of the debug log

Description of problem:

I encountered an issue when working with 64 bit Javas in our Jenkins environment, when I was trying to import the JBoss Fuse 6.2.1. resource to JON. For some reason, the problem does not occur when I switch to 32 bit Java.
The debug log shows that the plugin is unable to extract the JMX service URL :

Maybe this is issue related to (I found, that RHQ plugins use sigar in version 1.6.5):
https://jira.hyperic.com/browse/SIGAR-231

A piece of the agent debug log is attached.


Version-Release number of selected component (if applicable):

Version of the JMX plugin is : rhq-jmx-plugin-4.12.0.JON330GA.jar
I was using the newest JON plugin pack for JBoss Fuse


How reproducible: Use machines from our middleware jenkins environment for running of JBoss Fuse and JON agent and try to import it into JON inventory.
