+ <P align="left">As of Mac OS X release 10.1.1 there still appear to be
problems in the
+ Apple implementation of the Java 2D API's. The true source of
+ these problems and/or work arounds have yet to be identified (although
+ the problems appear to be closely tied to a 'gstack underflow' error
+ messages from the Apple JVM). We are interested in finding the source
+ of these problems and reasonable work arounds, so if you know what
+ causes these errors the Batik team would be very interested in hearing
+ from you (either directly or through the user/developer mailing lists).
+ </P>
+
+ <P align="left">Other things to be aware of on Mac OS X, due to fixes
for other
+ problems with Java 2D under Mac OS X, you may find that some filtering
+ operations take significantly more memory than on other platforms.
+ This will be especially true for deeply nested filter trees (where the
+ result of one filtering operation is filtered by another filtering
+ operation).</P>
+
+ <P align="left">Finally a few hints on avoiding problems under Mac OS
X. The bugs
+ seems to be triggered by filters (I've never seen a pure raster SVG
+ document 'mess up'). The use of the 'filterRes' attribute on the
+ 'filter' element seems especially problematic. The bug isn't 100%
+ reproducible, so while some content has the problem a lot if you play
+ with the document enough it will often 'fix' it's self for a while,
+ then after a while it will go back to being broken (this makes me
+ think the problem may be some sort of race condition in the JVM).</P>
