I got:
this.workingMemory.getClass().getPackage()
(java.lang.Package) package org.drools.reteoo, Drools :: Core, version
5.3.0.Final

I got no results back but I ran the search in JBoss Studio against the
binaries. Not sure this search should work.
Not on the binaries (presuming you mean
the .class or .jar files by that),
but run that search on your source files (.java files).
Yes I can see the two classed when I search for the types in the
IDE.
Anything else I could check?
I have been playing with the hashCode implementations of the facts and
planning entity but still no luck. I am assuming Expert is very dependant of
the hash code results.
The standard Java equals-hashcode contract must be fulfilled
(same
restriction as keys that are put into a java.util.Map).
So if A and B are equals(), then A and B must have the same hashcode.
And if A and B have a different hashcode, then A and B must be !equals().
(Note: but if A and B have the same hashcode, then A and B might or
might not be equals()).
See javadoc on java.lang.Object#equals().
For an update of a fact in the working memory, would
Expert expect the hash to change between the original fact and the new
updated one?
No.
Take a look how I do it in the examples.
If this all doesn't work, can you copy the full error message, the drl,
the move file and the planning entity class file?
