I am using env-mode DEBUG. I ran the test 4 times (2x ok, 1x crash, 1x ok).
Output of the 3 successful runs were exactly the same (except for timestamps of course).
Filed a Jira Issue: https://issues.jboss.org/browse/DROOLS-18

Look like a bug in mvel, nothing related with Planner,
File a jira in Drools Expert.
https://issues.jboss.org/browse/DROOLS
Important: is your planner run 100% reproducible (ignoring this
issue)?
So, if you do 2 runs, with logging debug, do you get the exact same
output?
In the examples, this is the case.
