Just because the memory usage stays high that doesn't mean there is a memory leak.. because Batik (and other classes) use weak and soft references to cache stuff.
If you eventually get an OOM no matter what the max heap size, then that's a memory leak. But you don't know what's the culprit unless you do a heap analysis, e.g. try "jmap -histo", etc. On Jan 15, 2008 4:26 PM, ACE91 <[EMAIL PROTECTED]> wrote: > > Hello again. > > I have finished my Batik-powered game (you can play it at my website, > sector91.com), but it tends to cause OutOfMemoryErrors.
