Package: fop
Version: 1:0.93.dfsg.1-2
Severity: grave

[It is possible that fop works for other people, in which case this 
would merely be important.  Feel free to adjust.]

When transforming the attached file, I get the following messages:

The default Java implementation is icedtea, but it occurs when using gcj 
as well.  Sun Java is not installed.  This bug is not fixed in 0.94; I 
tested.  I gzipped the testcase because it is 239k uncompressed, which 
is too large for email.  I also tried disabling the /etc/fop.conf file 
that I use, but this did not affect anything.

This problem can be trivially reproduced with
   fop -fo an-orange-in-flight.fo -pdf an-orange-in-flight.pdf

If you would like the DocBook 5.0CR4 source and the stylesheets used to 
transform it, I can tell you where to download them from.  Note that 
checking them out will require a HEAD version of git and some setup, 
which is why I just provided the XSL-FO.
