When using c3p0 and mysql, saving an object that contains an embeddable with at least one column annotated with @Lob throws:

java.sql.SQLException: Start position [1] cannot exceed overall CLOB length [0]

This is the same bug as HHH-5704. I am opening a new one and attaching a test case, as Gail Badner's comment on 21/Sep/11.
