Attached to the CCC proposal corresponding to this bug report is the latest JSR-201 spec draft for enum types (labeled "Preliminary Proposed Final Draft 2"). There are three substantive changes in this draft:
(1) All enum constructors are implicitly private. The compiler should implement this behavior.
(2) The use of the abstract and final modifiers on enum types is prohibited. The compiler should generate a compile-time error if a program uses either of these modifiers on an enum-type.
(3) It is illegal to reflectively instantiate an enum type.
Constructor.newInstance() will need new checks. (Class.newInstance() should then behave properly as it is implemented in terms of Constructor.newInstance().)
