Mark Proctor commented on JBRULES-1816:
---------------------------------------

I can't see what would cause this, or figure out how to re-create it. Can  you create a failing unit test for us? Look at the examples in MiscTest to see how we create unit tests:
http://anonsvn.labs.jboss.com/labs/jbossrules/trunk/drools-compiler/src/test/java/org/drools/integrationtests/MiscTest.java

Ideally please do this against trunk, or last 5.0.x M release.
