THashSet contract violation - 25 reports & coming

[neuro159]

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() or TObjectHashingStrategy.equals()) but their hashCodes (or those calculated by your TObjectHashingStrategy) are not equal.This violates the general contract of java.lang.Object.hashCode(). See bullet point two in that method's documentation. object #1 =\array (class java.lang.String), hashCode=-1567995011; object #2 =\array (class java.lang.String), hashCode=-1567995011
