David Keen created PIVOT-861:
--------------------------------
Summary: Memory leak: Window icon ImageListenerList retains
reference to closed windows, preventing garbage collection
Key: PIVOT-861
URL: https://issues.apache.org/jira/browse/PIVOT-861
Project: Pivot
Issue Type: Bug
Components: wtk, wtk-media
Affects Versions: 2.0.2
Environment: Windows XP, Java 1.7.0_05
Reporter: David Keen
Priority: Minor
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.
