Hi ...
An update to this issue.
After using the ToolkitImage for a while we started getting stack
overflows...
Exception in thread "AWT-EventQueue-0" java.lang.StackOverflowError
sun.awt.image.ImageWatched$WeakLink.isWatcher(ImageWatched.java:84)
The culprit was an infinate/circular list of ImageWatched.
toolkitimage.imagerep.watcherList
I traced it to(and could be others as well)
OMRasterObject.java(503) in OMRasterObject.setImage(Image ii)
There were repeated cals to :
Toolkit.getDefaultToolkit().prepareImage(bitmap, -1, -1, this);
on the same image(since I was reusing the same image).
I Changed it to retur/use BufferedImage, which now eorks and it seams to
have solved the problem.
I'll post more details if I do anything elses with it.
