Hi Chintan,

Implicit locking is not the same as optimistic locking.

By implicit locking I meant the database locks which are obtained
automatically when you obtain a connection. This level of locking depends on
the isolation level in use. I probably should have referred to it as
isolation level locking to avoid confusion.

I'm doing a little guessing here, I don't know that the isolation level is
the cause of the lock timeout, it just looks likely since there's no sign of
OpenJPA locking the table (the UPDLOCK statement).

Hope this helps,
