>             Project: OpenJPA
>          Issue Type: Bug
>    Affects Versions: 2.0.0

> When using openjpa.LockTimeout with H2 database we see Lock timeouts when trying to lock a table (using LockType.PERSIMISTIC_WRITE). Even with LockTimeout of 60000 this happens. So we set the LockTimeout directly via SQL and everything works as aspected. The SQL to set the timeout is:
> SET DEFAULT_LOCK_TIMEOUT 60000;
> The exception is :
> Timeout trying to lock table "MAILBOX" [50200-134] {prepstmnt 18507774 
> SELECT t0.mailboxId, t0.lastUid, t0.messageCount, t0.name, t0.size, 
>         t0.uidValidity 
>     FROM Mailbox t0 
>     WHERE (t0.name = ?) 
> [params=(String) #mail.INBOX]} [code=50200, state=HYT00]
