My image viewer application shows a massive memory leak when running on jamvm with classpath cvs (2006.06.06) - about 10..30 MBytes of memory per medium-sized image.
Goto http://tams-www.informatik.uni-hamburg.de/personal/hendrich/niffler/ and download niffler.jar and optionally the sources. Run the jar and specify the name of a directory with lots of images in it: jamvm -jar niffler.jar /home/hendrich/images/ The app should start up now (note that it also might just crash immediately after the first repaint; jamvm just hangs) and displays the first image. Move the mouse over the image, activate the popup menu and deselect popup > thumbnails > enable thumbnails, because creating the thumbnails may take a long time. Open the popup menu and select popup > slideshow > start slideshow (linear) or type "F9". Optionally, type "i" or select popup > slideshow > half interval to reduce the delay between images. Observe memory consumption... I have no simple testcase yet, because some image operations seem to happen asynchronously. I suspect that the loaded images are never garbage-collected. (It also might be the scaled image drawImage(x y w h x y w h), but this seems to work in my circuit simulator.) -- Summary: Massive memory leak in Graphics2D image operations Product: classpath Version: 0.92 Status: UNCONFIRMED Severity: normal Priority: P3 Component: awt AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: hendrich at informatik dot uni-hamburg dot de http://gcc.gnu.org/bugzilla/show_bug.cgi?id=27917 _______________________________________________ Bug-classpath mailing list [email protected] http://lists.gnu.org/mailman/listinfo/bug-classpath
