Kathey Marsden commented on DERBY-4856:
---------------------------------------
I think this is indeed a session ending exception so it makes sense to get the
javadump when it occurs and the thread dump might be very useful at this point.
If under some circumstance someone had intentional interrupts where this was
expected, they could set property higher to avoid the javacores, so +1 to the
change.

> On system crash or session ending error, Derby should dump as much
> information as possible. Such as: forcing a javacore if possible or at least
> thread dump and system environment information. This should only occur if a
> running session crashes not on boot error due to fail recovery etc.
> The IBM jvm provides a way to programmatically dump a javacore. i.e.
> com.ibm.jvm.Dump.JavaDump() And, the SUN jvm will force a thread dump using
> the Unsafe class and there may be a better way.
