----------------------------------------

Mark,

I don't understand how the engine can differentiate between a Java1.4 Enum and a regular Object type. We may be able to do something for Java 1.5 (trunk), but I don't see how to improve that for Java 1.4 (4.0.x branch).

> If I'm doing a pattern constraint, say "< 50" on a field, and that field is type java.lang.Object, with a value of type java.lang.Integer, a ClassCastException is generated at run time, although there is no compile-time error saying that this is an illegal constraint.
