Unobserved Exception Handler
interface UnobservedExceptionHandler
Interface for handlers invoked when a failed Task
is about to be finalized, but the exception has not been consumed.
The handler will execute in the GC thread, so if the handler needs to do anything time consuming or complex it is a good idea to fire off a Task
to handle the exception.
