--------------------------------------------------
Rick Wagner <rwagner(a)redhat.com> made a comment on [bug
852817|https://bugzilla.redhat.com/show_bug.cgi?id=852817]
+++ This bug was initially created as a clone of Bug #851234 +++
Description of problem:
Since Drools 5.3.0.CR1 concurrent creation of different knowledgebases from filesystem DRL
rule definition leads to illegal bytecode.
Reproduceable with Janino and eclipse compiler.
I have a maven based test project which executes the unit tests in parallel, this is the
result:
runFirst(de.trion.drools53.TwoTest): -1
runFirst(de.trion.drools53.FourTest): (class:
de/trion/drools53/Rule_When_a_user_is_young__print_his_name_DefaultConsequenceInvoker,
method: equals signature: (Ljava/lang/Object;)Z) Expecting to find integer on stack
runSecond(de.trion.drools53.FourTest): (class:

Workaround: synchronize access
