I installed Hibernate Tools on the config below.

In the "Hibernate Console" perspective, every time I give the focus to the a "HQL Scratchpad", I get a "An error has occurred. See error log for more details".

I give the complete stacktrace below...

Anyone has an idea of what is causing this error ? This is the only problem I'm encountering. The rest seem to work fine.

Thanks a lot.

----

Hibernate version: 3.1.2, I'm also trying 3.2cr1 to see if there's a difference.
Database : HSQLDB and hbm2ddl.auto=update
Eclipse : 3.1.1, build-id : M20050929-0840
