Description Nobody - feel free to take it CLA 2009-03-12 05:20:11 EDT 
Build ID: M20090211-1700

Steps To Reproduce:
See example code :

public enum Test
{
   
   TEST_ENUM(FORWARD_REF)

   private static final int FORWARD_REF = 0;

   private int i;
   private Test(int i)
   {
       this.i = i;
   }

}


More information:
The current (1.6 update 12) Sun compiler implementation allows this.

I believe problem is probably related to the fix for bug 255452 not checking for this case.

Comment 2 Frederic Fusier CLA 2009-03-12 12:34:23 EDT 
This is not a duplicate, just an invalid forward reference rejected by all compilers...
Comment 3 Frederic Fusier CLA 2009-03-12 12:34:45 EDT 
Close as INVALID
Comment 4 Frederic Fusier CLA 2009-03-12 12:43:50 EDT 
I forgot to log the error I got while compiling comment 0 test case with Sun JDKs...

Using Sun JDK 6.0:
java version "1.6.0_14-ea"
Java(TM) SE Runtime Environment (build 1.6.0_14-ea-b01)
OpenJDK Client VM (build 14.0-b10, mixed mode)
Test.java:4: illegal forward reference
   TEST_ENUM(FORWARD_REF);
             ^
1 error

Using JDK 1.5.0:
java version "1.5.0_18-ea"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_18-ea-b01)
Java HotSpot(TM) Client VM (build 1.5.0_18-ea-b01, mixed mode)
Test.java:4: illegal forward reference
   TEST_ENUM(FORWARD_REF);
             ^
1 error

Also forgot to mention that that test case was missing a ';' at the end of TEST_ENUM(FORWARD_REF) line and that I added it to avoid other noisy compilation errors...

My apologies. If i had double checked my code this bug would indeed have been a duplicate of 255452. My intention was to report the bug defined there.
Comment 7 Olivier Thomann CLA 2009-03-12 13:15:05 EDT 
I guess you meant:
TEST_ENUM(Test.FORWARD_REF);
Closing as VERIFIED.
Comment 8 Nobody - feel free to take it CLA 2009-03-12 13:15:54 EDT 
Yep...
