Version-Release number of selected component (if applicable):
JON 3.1

How reproducible:
Always

Steps to Reproduce:
1. Install JON system and add one or more resources to inventory
2. Locate a valid resource ID for a resource in inventory - probably 10001
3. Execute the following from the JON CLI:

ResourceManager.getLiveResourceAvailability(10001)

  
Actual results:
        Wrapped java.lang.RuntimeException: [Warning] javax.transaction.RollbackException: [com.arjuna.ats.internal.jta.transaction.arjunacore.commitwhenaborted] [com.arjuna.ats.internal.jta.transaction.arjunacore.commitwhenaborted] Can't commit because the transaction is in aborted state (<Unknown source>#1)
ResourceManager.getLiveResourceAvailability(10001) 
^


Expected results:
The live availability for the resource with ID 10001 (in my case Platform).
