[jboss-jira] [JBoss JIRA] (DROOLS-9) Exception in User-defined Java method when rules are optimized by the JIT compiler

[Andreas Bentele (JIRA)]

     [ https://issues.jboss.org/browse/DROOLS-9?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andreas Bentele updated DROOLS-9:
---------------------------------

    Description: 
I watched this issue after upgrading from Drools 5.3.1 to Drools 5.5.0.Final.

I didn't find any trivial example, so I reproduced the error with a non-trivial test case, and attached the test case to this issue. The output is listed in the field "Steps to reproduce":

What does the application:
- it calls the rule "DroolsJITTest-Rule" 20 times - 20 is the threshold for jitting. In the output, you can see the line "Service.getAllTimers" 20 times.
- after that output, a exception during jitting is thrown, because com.sample.Service.getTimePerStroke(Service.java:42) throwed an exception
- this service is called in the LHS of the rule

But:


Code of the rule:
{code}
rule "DroolsJITTest-Rule"
when
	$service : Service() 
	p: PulseEvent(
		$actionTimestamp : actionTimestamp,
		$eventTimestamp : eventTimestamp
	)
    t: TimerToken(
		$machineId : id,
		$timestampUTC : timestampUTC,
		$service.getLongValue(service.workplaceIdForMachineId($machineId, $actionTimestamp), "RC.WORKPLACE_LEADING_OPERATION_ID") > 0,
		service.getTimePerStroke($service.getLongValue(service.workplaceIdForMachineId($machineId, $actionTimestamp), "RC.WORKPLACE_LEADING_OPERATION_ID")) > 15
	) from $service.getAllTimers("RC.MACHINE_STROKE_TIMER")
then
    System.out.println( "Rule executed" );
    update(p);
end
{code}
