In case anyone is confused when they read the draft.mode work-around in
the Debian bug, I'll try to explain here.

The Debian bug reporter's FO document did not originally contain images.
When FOP produces a draft output (draft.mode=yes), it inserts a
background image that says "DRAFT" or something like it on each page, as
a sort of watermark.  This image insertion causes his crash.

My input documents do contain images (screenshots of our software), so
disabling draft mode (and removing the background image) doesn't help
me.  They still contain images, and FOP crashes.

Bug description:
I'm not sure if this bug needs logged against Ubuntu's OpenJDK project because a similar issue is logged in Debian's bug list as #447951 (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=447951).  I couldn't find a statement about what qualifies as "up-stream" for the OpenJDK packages, but this appears to the an identical problem.

To summarize from the Debian bug, I'm running Apache FOP with openjdk-6-jdk on AMD64 (version 6b11-2ubuntu2, but 6b11-2ubuntu3~ppa1 from the PPA acts the same) and I see a NullPointerException when processing documents with FOP when an image is inlined.  I don't get this error with Sun's 64-bit JDK 1.6.0_03-b05 (later updates are problematic with Eclipse so I haven't tested them).

I can supply the FO input document if that would help (it simply inlines one PNG).  The Debian bug has an FO document attached.
