JmsXA shows unavailable in JON if the ${JBOSS_HOME}/server/<INSTANCE> contains special characters in <INSTANCE>

Issue

• When the path ${JBOSS_HOME}/server/<INSTANCE> contains special characters in <INSTANCE> the agent reports that JmsXA is not available.
• There seems to be something in the agent code that prevents special characters (hyphen and underscore anyway) from being used in the instance.
