[rules-users] Drools 5.4 - Can't catch Exception

So I keep getting the exceptions below. I have surrounded the fireAllRules
with a try catch throwable block to try and debug this but I never seem to
be able to catch it. This only happens in the first couple 100 invocations
of the fireAllRules then never happens again(sometimes it never happens at
all). Is there a way to handle this exception or prevent it from happening?
I am assuming that this is occurring do to an activation being evaluated
after the OrderSideContext is retracted from working memory. Anyone else run
into a similar issue?
TIA
