-/**
- * This class tests some internal hashCode() functions.
- * Bug #4170614 complained that we had two iternal classes that
- * break the invariant that if a.equals(b) than a.hashCode() ==
- * b.hashCode(). This is because these classes overrode equals()
- * but not hashCode(). These are both purely internal classes, and
- * the library itself doesn't actually call hashCode(), so this isn't
- * actually causing anyone problems yet. But if these classes are
- * ever exposed in the API, their hashCode() methods need to work right.
- * PatternEntry will never be exposed in the API, but IntHashtable
- * might be. This is a shell test to allow us to access classes that
- * are declared package private.
