Sandro Martini commented on PIVOT-861:
--------------------------------------
A small update, is sources I found many places where there is something like
this:
Image iconLocal =
(Image)ApplicationContext.getResourceCache().get(iconURL);
then, if the resource/image is still null, try to load it in a try/catch block,
then put it in cache, like:
ApplicationContext.getResourceCache().put(iconURL, iconLocal);
but I'd prefer to move the put in cache inside try blocks ...

>
> 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.
