I fully agree that we should remove the try/catch block inside JEventProcessorPODIO and let crashing factories crash rather than attempting to keep going. Most of the crashing factories are excepting because there is a JEvent::Get() for some T that is not present in the input file (due to geometry, etc). We can use the non-excepting forms of Get/GetSingle, or we can wrap them in the try/catch block instead.
