While I appreciate the sentiment, I'm afraid they'll want something in
the form of white papers or "expert testimonial". My word alone is of
little use.
Personally I'd suggest putting the logic into a normal PL/SQL
procedure, then just calling it from the java if you want the code
re-use. They are trying to put it all into the java for code-reuse.

You need to avoid putting this crap in the database. So use any means
for that - tell your developer that it's slow by design, that it's
compiled on the fly into a bunch of SELECTs and PL/SQL code, tell him
that it cases all kind of ORA-600 (you wouldn't be far from truth).
You target should be to convience him to convert it to PL/SQL and make
sure he doesn't become a PL/SQL developer in one week - nothing worse
than Java developer writing code in PL/SQL! ;-)
