I have been doing a little bit of testing with the current Trunk code

OutOfMemoryError. I think it is safe to assume that the memory leak
exists in the current 0.94 branch also. I am keen to avoid releasing
FOP whilst the code contains such a problem.
If anyone is interested I can send you the FO file and test harness
code I use to repeatidly generate PS off list.
If there is anything special about that file, you could always post it,
but I'll try to see if I can reproduce with a simple FO without special
features. If I don't succeed, I might ask you to post your code as well.
The FO file has some SVG embedded in fo:instream-foreign-object.
Did you, by any chance, noticed a similar effect with other formats
(which would indicate the leak is localized in the fotree or layout- code)?
Yes, in one of the tests I was generating Area Tree XML with mimic
Renderer set to the AFP Renderer and observed OOME. So I don't think the
output format is relevant here.
One of my colleagues is going to profile FOP. I will keep you all
informed of any findings.
