Quite frequently with EAP 110.137 I'm getting errors like this:
Equal objects must have equal hashcodes. During rehashing, Trove discovered that the following two objects claim to be equal (as in java.lang.Object.equals()) but their hashCodes (or those calculated by your TObjectHashingStrategy) are not equal.
I've tried invalidating caches but it seems to have had no effect. The error doesn't seem to be causing any visible problem though.
