PDF transform fails with "CPF6DF4 Object QCTXPDF in library QSYS contains unrecognizable data"

I have the following toy program which I would expect to transform my spool
files on our V6R1 host to PDF (just an example) and give me the bytes of the
PDF file as a PrintObjectTransformedInputStream. Unfortunately it fails
with



Exception in thread "main" com.ibm.as400.access.AS400Exception: CPF6DF4
Object QCTXPDF in library QSYS contains unrecognizable data.

To run the program as-is, create ?axs.properties? in your home directory ?
sample content:



as400.user=tra

as400.password=?

as400.hostname=hostname



I have verified the other day that the system can use the ?override
printerdefintion to capture print from job into a PDF stream file? trick, so
the mechanism is in place.



Suggestions on where to look or what I have missed? We are up to date on
PTFs etc. I am using jtopen-5.0 from Maven central (if that should matter).
