Perhaps that is the case, but it is not entirely clear from the history.  The exception was
added before we had CREATE FUNCTION and CREATE PROCEDURE syntax, so there never were tests
for that so it good Rick is adding it.

On the patch, I think it would be good to enable this test for client to make sure lob parameters
are working properly there too.

> Derby objects if you try to declare a function or procedure with an argument whose type
is BLOB or CLOB. These kinds of arguments are allowed in the SQL standard and the matching
Java types are java.sql.Blob and java.sql.Clob. See the SignatureMatching.html summary attached
to DERBY-3652.
> We should lift this restriction and allow functions and procedures to take large object
arguments.
