I've never seen this error before. Did you tried Drools 5? The error still happens? Can you recreate in a junit test case?

Hi all,
Using 4.0.7.
I am getting this null pointer when doing an Insert into working memory.
I know the object I am inserting is not null.
java.lang.NullPointerException
at org.drools.util.PrimitiveLongStack$Page.remove(PrimitiveLongStack.java:137)
at org.drools.util.PrimitiveLongStack.pop(PrimitiveLongStack.java:69)
at org.drools.common.AbstractFactHandleFactory.newFactHandle(AbstractFactHandleFactory.java:44)
at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:785)
at org.drools.common.AbstractWorkingMemory.insert(AbstractWorkingMemory.java:684)
Any idea what might be causing this?
Scott
