Sandro Martini commented on PIVOT-861:
--------------------------------------
Just committed the fix for the second, smaller leak: Committed revision 1366096.
Note that other (much smaller) memory leaks still seems to happen, but we can
see them later if needed (some seems too much complex to track).
To have an idea, after approx. 10.000 dialog open/close tests with Pivot861,
now the memory still use near 40 / 45 MB (using the latest JRE 6 under Windows
32) , you can see this even from Task Manager, or for example VisualVM.
David, thank you again very much for your help here.

> When a window or dialog is opened which has an icon, after it is closed it
> cannot be garbage collected because a reference is retained to it through the
> icon. 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.
