> I've found that after a sequence of queries, starting new transactions and clearing the session, a Blob will not be successfully from the database and null will be returned by the InputStream instead. Using the debugger I've followed this into the jdbc code and from what I can tell some message is sent to load the blob but the database replies with an empty set of data which naturally causes the InputStream to read null.
> I've attached a test case (sorry, no makefile or pom.xml, I just ran it using eclipse) which, for me, replicates the bug.
> Note I've also used hsqldb and mysql and didn't see the bug with them, only postgresql.
> thanks,
> Aaron
