Enable new Eclipse 4.7 "unlikely-arg-type" warning

Browse Source 
The only outstanding instances of this warning are in test code that is
asserting that OperatorPredicates do not compare equal to Strings. These
asserts are arguably overkill, but arguably also a reasonable test of an
equals implementation. Ignore the warning in these cases.
