java.lang.IllegalArgumentException: 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.This violates the 
general contract of java.lang.Object.hashCode().  See bullet point two in that 
method's documentation. object #1 =KW_OPERATOR; object #2 =KW_OPERATOR
