HI, I am getting the following exception while loading the data:
(Full stack trace at the end)

Trivia:

Database: PostgreSQL 7.4
Relevant Mapping:
<class name="User" table="LB_USER">
......
<property name="contacts" column="CONTACTS" type="serializable" length="65535" />
..........
</class>

Database column type: bytea.

Any clues on whether the issue is with the mappings OR with hibernate layer would be great.
