Error executing timer job when reusable subprocess is executing

[ghollins]

Hi,

   I have a process where there is a parallel gateway, and on one of the paths, there is a "duration" timer.  If the timer happens to fire while the "call activitiy" (the one at the bottom of the picture) is running, I get an error:

10:55:17,472 ERROR [org.jbpm.process.instance.timer.TimerManager] (pool-26-thread-1) Error when executing timer job: org.drools.core.RuntimeDroolsException: Unexpected exception executing action org.jbpm.process.instance.event.DefaultSignalManager$SignalProcessInstanceAction@392bfc

Is there a way to work around this?  In other words what I really want is that if the timer can still exist in the process, but if it fires during another task, it will either be ignored, or simply wait until the other task is done.  When the above error happens it ends up killing my entire process.

Thanks,

looking at the stack trace it looks like there is another error that is actually thrown and the one reported back to the caller is when assembling the exception for error handling. This was already fixed post 6.0. What would be good to check is to debug it and see what is the error on timer execution.

Anyway, if you could provide test reproducer and jira I will look into it.

Hi,

   Is there a place I can download the full installer zip for the post 6.0 codebase?

(similar to http://sourceforge.net/projects/jbpm/files/jBPM%206/jbpm-6.0.0.Final/)

Thanks,

you can take it from jenkins server. Although in come cases it might be unstable as it's under development.
