[rules-users] Complete Solutions Tabu Question

Hello Drools Users. Do Solution objects need to implement equals() and hashCode() methods in order to take advantage of the completeSolutionsTabuSize configuration? I did a little digging through the code and it appears that Solution objects are being compared with their clones (implicitly that is, they are being used as map keys). AbstractTabuAcceptor:87 The documentation mentions that moves need to implement equals and hashCode, but doesn't talk about Solution needing it. Thanks in advance, Steve
