Michal Letynski created DROOLS-968:
--------------------------------------
Summary: Random Nullpointer
Key: DROOLS-968
URL: https://issues.jboss.org/browse/DROOLS-968
Project: Drools
Issue Type: Bug
Affects Versions: 5.6.0.Final
Environment: Windows, Jetty
Reporter: Michal Letynski
Assignee: Mark Proctor
From time to time i.m getting weird Nullpointer exception. I
didn't reproduce the problem when the app is deployed on Glassfish. Only on jetty and
only on windows system (with MAC OS everything is ok)
Stacktrace:
java.lang.NullPointerException
at
org.drools.base.evaluators.EvaluatorRegistry.addEvaluatorDefinition(EvaluatorRegistry.java:155)
at org.drools.base.evaluators.EvaluatorRegistry.<init>(EvaluatorRegistry.java:77)

at org.drools.compiler.PackageBuilder.<init>(PackageBuilder.java:308)
at org.drools.compiler.PackageBuilder.<init>(PackageBuilder.java:236)
And my code is a simple object creation:
PackageBuilder packageBuilder = new PackageBuilder();
Any hint why this might occur ? Or should i just ignore it because on production we have
Glassfish server ?
