We ocassionally see errors in user code such as
java.lang.IllegalStateException: run: Caught an unrecoverable exception

But it doesn't provide a lot of information about the actual stack trace in the
user land code of the callable. We can wrap the invocation of the
Callable#run() to get access to this stack, which can be very helpful for
debugging user code.
