Comments
EVALUATION In the passed in test case the Image will be loaded using Toolkit.getDefaultToolkit().createImage(path), this code has not changed in ages. I would suspect what is happening is that at some point it is determined a VolatileImage can be used to speed things up, when the screen is locked the VolatileImage is likely blown away and we probably don't realize we need to recreate it. Reassigning to 2D for further analysis. ###@###.### 2002-04-26 Closing as a duplicate of bug 4664818. ###@###.### 2002-05-17
