Subject [jira] Commented: (LANG-76) [lang] EnumUtils.getEnum() doesn't work well in 1.5
Date Fri, 19 Feb 2010 19:58:27 GMT

    [ https://issues.apache.org/jira/browse/LANG-76?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12835922#action_12835922

Niall Pemberton commented on LANG-76:
-------------------------------------

I added a test case for this:

  http://svn.apache.org/viewvc?rev=911954&view=rev

And I tried testing using Sun's JDK 1.5.0_01 and 1.5.0_22 on a Windows XP machine and I cannot
reproduce it.

Can anyone see whats wrong with my test case - or provide one that can reproduce the error?

> 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
