Description

We are using FOP to generate big PDF files, so we have to use the -conserve option to save memory.

After updating from version 2.2 to 2.3 FOP aborts throwing a NotSerializableException.

I was able to reproduce the issue using a few small fo files. Without -conserve, the PDF is generated successfully, with -conserve option processing fails.

Attached are the sample fo files to reproduce the problem as well as the full output printed by FOP.

command used: fop.bat -conserve out.fo out.pdf
