Description:

When using @Lob on a String-typed attribute, with a column of type text in database, I get this while fetching data (the french exception message says something like "the SybResultSet.getClob(String) method is not supported and should not have been called."):

java.lang.UnsupportedOperationException: La méthode com.sybase.jdbc4.jdbc.SybResultSet.getClob(String) n'est pas supportée et n'aurait pas dû être appelée.

Note: I'm currently migrating from Hibernate 3.5.3-Final to 4.1.9.Final, and everything was working fine before the upgrade. Migration guides didn't tell much about LOBs, so I changed nothing @Lob-related in my code/mapping.

As the HibernateCoreMigrationGuide36 wiki page suggested for other database systems, I tried leveraging the hibernate.jdbc.use_streams_for_binary configuration parameter, but to no avail.

This issue may be related to HHH-3691 or HHH-3892.
