There is a StatusService for each Application that does exactly what is suggested, it catches any Throwable (Exception and Errors), logs the exception and sets the status to InternalError. It is implemented as a filter in the NRE.
As Resource.getVariants() doesn't declare any exception, it may be necessary to wrap your JSONException into a RuntimeException. Is that an issue?
