3:28 p.m.
I am using Drools Planner 5.5.0.Final.
During the running of a unit test I sometimes get a crash with stack-trace shown beneath.
It does not happen all the time, just now and then.
But if it happens the process terminates and no solution is reached.
Any ideas on this?
The stack-trace does not show a lot on which rule is failing...

New subject: [Error: incompatible types in statement: boolean (compared from: class be.axi.planner.domain.Task)] - mvel bug
is your planner run 100% reproducible (ignoring this issue)?
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

Michiel Vermandel

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.
