Error actually seems to indicate the recon failed (the pair of NegativeArraySizeExceptions) on a JEVIO error. Then the DQM job ran on the empty LCIO file (the "0 events" message) and failed (NullPointerException in SvtMonitoring.endOfData()) because there's some DQM drivers that don't cope well with empty histograms. I grabbed file 5754.4 and confirmed that JEVIO fails to read the file - the problem is not in the hps-java recon.
