Comment 1 Olivier Thomann CLA 2004-11-04 14:46:49 EST 
The workaround is to set the workspace compiler preference to be 1.5.
You can then add the implemented method. It doesn't handle the fact that the
method needs to be added after the enum constant. So it doesn't add the extra
semi-colon required.
I think this should be fixed by use DOM/AST inside the jdt/core operations.

Is it ok now?
