FOP infinite loop

Hi

I got a strange behavior,
which goes into infinite loop,
for converting PDF with Apache FOP.

> fop.bat -c conf\userconfig.xml test.fo test.pdf
.....
.....
[INFO] area contents overflows area in line
[INFO] area contents overflows area in line
[INFO] area contents overflows area in line
-- infiniet loop --

I found an article that indicates
how to avoid the same problem.
http://lists.oasis-open.org/archives/docbook-apps/200402/msg00244.html

According to this article, one of solutions is
to specify an exact value of termlength
at variablelist elementin in table.xsl.
I made, therefore, a change in
docbook/fo/table.xsl:<variablelist termlength="100">,
but it doesn't work anyway.

I wonder if I misinterpret the suggestion of the article.
I wish experts would give ideas.
