Sandro Martini commented on PIVOT-861: -------------------------------------- Just for reference, some useful articles on eclipse and how to find memory leaks with its Memory Analyzer Tool (MAT): http://www.bonitasoft.org/blog/eclipse/acquire-heap-dump-from-mat/ http://www.bonitasoft.org/blog/eclipse/an-effective-way-to-fight-duplicated-libs-and-version-conflicting-classes-using-memory-analyzer-tool/ Note that FindBugs say nothing during analysis of sources ... > 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 > Assignee: Sandro Martini > Priority: Minor > Fix For: 2.0.3 > > Attachments: leaktest.zip > > > 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. -- This message is automatically generated by JIRA.
