I’ve confirmed, and written a reduced test. Please monitor the new thread on drools-dev. Also don’t forget to make a JIRA.

Hello,

any news ?  Should I create an issue in JIRA ?

Here is another zip (I removed the test in relation with another issue:
DROOLS-421).  The right method method to execute is
testLeftTupleIndexHashTable()

Also as a tip, turn on TRACE mode, for the logback.xml, and post back the
results.

you have two drl files. One with two rules, one with one rule. Which is
the rule you were adding and removing to see the bug?

Can you paste the 3 rules, that cause the issue? We’ll see if we can
gleam
something from that, while we wait for your unit test.

Hello,

I keep trying to migrate drools from 5.5 to 6 on my project.  I found
a
second regression/issue.  I'm trying to produce a unit test for
6.1.0-SNAPSHOT but I face some difficulties to determine the cause of
this
issue.  So I have a drl with 3 rules.  I'm a bit disappointed because
if
I
switch two rules (without modifying anything, just switch one rule
with
another in the drl file), the NPE disappears...
