Bug 886537

Created attachment 662378 [details]
drools-jon-example application

Description of problem:

When monitoring the Drools example application, the Operations with parameters for the Drools app session rise an IllegalStateException. The same application monitored by JConsole executes Operations with parameter without problem.

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

BRMS-5.2.0.GA/BRMS-5.3.0.GA/BRMS-5.3.1.CR1
JON 3.1.0.GA/3.1.2.ER3

How reproducible:

Always

Steps to Reproduce:
1. Install the JON 3.1.1 server and with BRMS plugin

2. Run a drools-jon-example application (attached zip)

with ant compile; ant server
     ant client.phase1; ant client.phase2

3. Discover the JMXServer and go to JMXServer > Drools Services ... > KSession {sessionId} to the Operations tab and execute eg Get statistics for rule with "hello world" parameter.

Actual results:

java.lang.IllegalStateException: Name [ruleName] specified for parameter of operation [getStatsForRule] on MBean [org.drools.kbases:type=my-own-knowledge-base,group=Sessions,sessionId=Session-1] is invalid. The MBean operation does not take a parameter by that name.

Expected results:

The Operations with parameter should return:
activationsCreated=1 activationsCancelled=0 activationsFired=1 firingTime=0ms
