--------------------------------------

Hi Knut. Yes, the problems with LOB return values from CallableStatements are half of the
reason that the existing patch is not ready for commit.

> 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.
