Here is another zip (I removed the test in relation with another issue:
DROOLS-421). The right method method to execute is
testLeftTupleIndexHashTable()
Drools-LeftTupleIndexHashTable-61b.zip
<http://drools.46999.n3.nabble.com/file/n4028138/Drools-LeftTupleIndexHashTable-61b.zip>
Here is the trace:
