Henri Yandell closed LANG-76.
-----------------------------

    Resolution: Won't Fix

Marking as wontfix as I don't see it being likely that anything will be done here.

Joe's suggestion is interesting, and if anyone would like to explore that, prove that it solves
the problem and attach as a patch, then please reopen.

> Hi,
> I encountered with problem using EnumUtils.getEnum() in 1.5. It appears that my
> Enum class should be accessed first so constructor will be called. In 1.4 it was
> enough to have myClass.class, so all static members were initialized. In 1.5 it
> doesn't work.
> I noticed that static members are not initialized anymore while acessing to
> class definition. See the code
> public class Test {
>     public static final class TT{
>         public static final TT one = new TT();
>         private TT(){
>             System.out.println("Called TT" );
>         }
>     }
>     
>     public static void main(String[] args) {
>      Class cl = TT.class;
>    // System.out.println( TT.one);
>   //  System.out.println(TT.class.isAssignableFrom(String.class));
>     }
> }
> In 1.4 constructor of TT is called, while in 1.5 is not. 
> Actually, according to the spec
> (http://java.sun.com/docs/books/jls/second_edition/html/execution.doc.html#57946),
> this is right behavior of Java. 
> Unfortunately, I didn't succeded to think about good solution..
> P.s. I know that in 1.5 we have enum built-in, but it is not the same, and we
> try to move to 1.5 without too much changes
