Not on the binaries (presuming you mean the .class or .jar files by that),
but run that search on your source files (.java files).

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().

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?
