Summary: enums can't appear in EnumSets

Initial Comment:
Due to the way DynamicJava-defined enums are implemented, the EnumSet API class doesn't recognize them as enums and throws an exception when trying to create a set of that type.

> enum Foo { A, B, C};
> EnumSet set
> set = EnumSet.allOf(Foo.class)
java.lang.ClassCastException: class Foo not an enum
	at java.util.EnumSet.noneOf(EnumSet.java:93)
	at java.util.EnumSet.allOf(EnumSet.java:110)
> 

Also got this type error, which should be looked at more closely:

> EnumSet<Foo> set
Static Error: Type arguments are invalid
