Hi,

You can catch OS signals in java, although there are different signals for
each OS. The following packages have signal functionality: sun.misc.Signal,
sun.misc.SignalHandler.
I have created test programs which can handle various signals sucessfully -
and it is these test programs which work (i.e. catch signals) when no jdbc
driver is loaded, and do not when the driver is loaded.
Check out the following url for a discussion about signals.
