Re: Re: [SQL] JDBC Statement.setQueryTimeout : is there plan to implement this?

java.util.concurrent introduces ScheduledExecutorService, which fixes a lot of the problems with java.util.Timer and introduces more features.

Specifically, it enqueues timed actions and executes them on a thread pool, providing good controls both for controlling individual tasks (canceling) and the entire pool (shutting down cleanly / immediately)

It might be a good fit for implementing timeouts.
