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...
[Error: incompatible types in statement: boolean (compared from: class
be.axi.planner.domain.Task)]
[Near : {... this == lead ....}]
