Jason, There was a bug raised on this with Sun, and it is as follows: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6434149 They are actually not going to fix this, but instead want you to use what you describe below. We will have to change our code accordingly in AS 5 and anywhere else for that matter to support JDK 6. Andy On Wed, 2007-06-13 at 17:12 -0500, Jason T.
