-------------------------------

hi,

remove the break statement is ok, but the log will grow a lot with a DB error in the loop of the Main#lock(). it would be great a sleep or incremental sleep

> Two part issue.
> 1) Oracle isAlive() method needs to poll its connection to DB to ensure connection alive.
> 2) Main#lock() remove second break statement - in the event of DB service loss this breaks the lock out of normal spin lock routine.
> I'll be supplying a patch for this issue.
