Hi Herv�
I would suspect that you are not cleaning up your
listeners. You either need to remove your listeners
or make sure your listeners go to GC otherwise they
can easily cause memory leaks. At this point Batik
has been pretty well tested for memory leaks and they
generally involve complex scenarios, just loading a
document repeatedly seems unlikely to cause the problem.

I use Batik in a Java application and have a Out of Memory error after
opening and closing several times big XML files. I first thought the
memory leak was due to my code, but I now think it is coming from Batik
(not a 1.6 regression, because I had these Out of Memory errors before
1.6).
I used Netbeans with the memory profiler with the batik built-in SVG
browser application (1.6 version), opening several times the "anne.svg"
SVG file, and the profiler shows that the "live" objects are increasing
for these classes, after each new opening :
- org.apache.batik.dom.GenericText
- org.apache.batik.dom.GenericAttr
- org.apache.batik.dom.AbstractElement.Entry
- org.apache.batik.dom.AbstractParentNode.ChildNodes
- org.apache.batik.dom.svg.SVGOMGElement
- org.apache.batik.dom.svg.SVGOMPathElement
- org.apache.batik.gvt.ShapeNode
- org.apache.batik.gvt.CompositeGraphicsNode
- org.apache.batik.gvt.event.GraphicsNodeChangeEvent
- org.apache.batik.ext.awt.geom.ExtendedGeneralPath
- org.apache.batik.dom.util.DocumentDescriptor.Entry
There is always one unique org.apache.batik.dom.svg.SVGOMDocument (same
for org.apache.batik.dom.svg.SVGOMDefsElement, for example), so I think
this is not coming from caching each previously opened SVG Documents.
I don't use the browser in my application, but I have the same results,
so I think this is not coming from the browser itself...
Anyone has a hint on the reason of these memory leaks ?
