Chris Dolan created JBRULES-3439:
------------------------------------
Summary: NPE in AbstractTabuAcceptor.stepTaken
Key: JBRULES-3439
URL: https://issues.jboss.org/browse/JBRULES-3439
Project: Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: drools-planner
Affects Versions: 5.4.0.Beta2
Environment: drools-planner-example 5.4.0-SNAPSHOT pulled via Maven on March 29.
I believe this corresponds to
https://github.com/droolsjbpm/drools-planner/commit/ba38344b7563830eb2a72...
Reporter: Chris Dolan
Assignee: Geoffrey De Smet
I know this is a weak bug report and I apologize in advance for that...
I'm writing integration tests for my solver configuration. My code seems to work in my
GUI (subclass of CommonApp) but it fails under my junit test. I'm quite new to Drools
and Planner so I wouldn't be surprised if the root cause is my fault, but I think a
NPE is bad news.
