I have just tried my project in drools 5.0.1 and get the same problem, I don’t think that I can be the only one to have hit this, I must be doing something wrong. I will investigate and report any findings.

No I am not using spring, I am using the Bitronix TM as described in the drools docs. I am using version 5.1. The thing I find strange is that there is no possible way for the field to be anything but null, it looks like it is just leftover from some old code, I am not sure why JPAProcessInstanceManager is trying to get the value either…

This could be related to TX management. I experienced this error while fixing some bugs in DroolsSpringJPAManager and DroolsSpringTransactionManager.

Are you using drools-spring integration?

Best,

Hi,

Is there some magic going on in ProcessInstanceInfo? As far as I can tell there is no way that the processInstanceId can ever have a non-null value. This causes a null pointer exception when called from JPAProcessInstanceManager line 37 because it will try and unbox null to a long.

Can anyone explain what is supposed to happen?

Thanks,
Greg
