| /** |
| * 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. |
