Roger Whitcomb commented on PIVOT-861: -------------------------------------- Recoded ListenerList again to use java.util.ArrayList as the implementation -- simplifies our code and eliminates what is basically duplicate logic already implemented in the core Java classes.

Removing the icon resolves the issue. > As far as I've investigated, the issue appears to the in the > ImageListenerList which each Image contains. I've done a heapdump of my > application and used the IBM HeapAnalyzer which shows this list containing a > reference to the window/dialog through the ImageViewSkin, but I don't know > the Pivot internals well enough to see where or how it should be released. > I'll attach a simple test application to show the issue. -- This message is automatically generated by JIRA.
