I suggest we get rid of the static abort. If RuntimeException happens,
check where it happens. The first use case looks suspicious as it just
returns if it's an instance of RE. For the 2nd case in DOM error report,
let's throw a RuntimeException with the specified error message if error
happens, and there's no handler or the handler failed to handle it.
(would be better than an empty RE)
