Thanks Dave, I'll keep this info in mind. In the meantime I have tried
the FOP "intermediate format" (IF) instead of the area tree, and I find
I can export that, change it, and then read it in and publish it with no
problems.

Hi Mark,
It might help narrow down on the issue if you tried an alternative JDK
- I'd suggest Temurin jdk-11
It might also be a good time to update to the latest FOP version.
I've tried what you're attempting to do on Temurin 11 / FOP main
branch and I had no issues.
Regards,
Dave

*Subject:* Publishing area tree XML fails
I'm using FOP 2.4 on ubuntu. I create an area tree XML file on the
command line with this:
fop -s topic.fo -at area_tree.xml
This works fine. I plan to make some changes and read it in, then
publish to PDF.
I am trying to read it in and I don't know what to expect, or how to
publish out to PDF. The docs do not go into this, that I can find. I get
failure when I run the command below intended to produce a PDF called
aaa.pdf:
fop -atin area_tree.xml aaa.pdf
[warning] /usr/bin/fop: JVM flavor 'sun' not understood

Any ideas?
