fop trunk hangs

Hi

Downloaded SVN trunk today.
Compiled fine.

I use gentoo and do have fop installed.
I was able to create a few test pdfs but when I tried to create the final version of my pdf it hanged.
I enabled debug logging with log4j and saw a StackOverFlow error.
That is when I started using the trunk version.

No more StackOverFlow errors but the pdf creation process hangs before completion. CPU usage 100%.

I tried the -fo -pdf AND the -xsl -xml -pdf route for fop from commandline and an ant script.

No luck.

I added debugging statements with XSLT function extension when using the -xsl -xml -pdf route.
I have chapters and paragraphs in them. I print the number of paragraphs when I enter a chapter and count them down as they are processed. It get to the last paragraph then hangs.

If I alter my source xml to include more than the one test chapter it hangs at the last paragraph without going on to the next chapter.
