A follow-up on some issues hinted at in the software meeting.

First, when producing readout and recon events, I am no longer able to read the events with LCIO.
It can print the header summary for all of the events, but when trying to read the actual collections, it crashes on the first event with:

java -jar /u/group/hps/hps_soft/lcio/collection_type_fix/trunk/target/lcio-2.4.4-SNAPSHOT-bin.jar print /work/hallb/hps/byale/hps-sim_test/old_mixing/wab-beam-tri_slic_readout_2018Aug15.slcio

Readout and recon can both still process the events, and fill the output collections without crashing.

However, when making DSTs or tuples from these recon events, the DST maker processes them (instantly), and all of the collections in the output DST are empty. Same with the tuple maker.


This is with recon made using an older, stable, well-tested jar (location: /u/group/hps/hps_soft/git/hps-java_current/hps-java_2017Dec28/distribution/target/hps-distribution-4.1-SNAPSHOT-bin.jar).

I never had a problem reading events made with it before, or making DSTs, so I thought it might be related to LCIO suddenly crashing. Using a jar updated today, I get the same issue with reading the events with LCIO, but the DST maker no longer even works at all, instead giving this error:


[ DST MAKER ]: Setting DST file name to wab-beam-tri_slic_recon_2018Aug15_singles1.root
 A runtime error has occured : [ SvtDataWriter ]: Track does not have a track state at the Ecal.


Can anyone reproduce this, or have any insight?


Readout command:

java -DdisableSvtAlignmentConstants -XX:+UseSerialGC -Xmx500m -jar ${hps-java} -r /org/hps/steering/readout/PhysicsRun2016TrigSingles1.lcsim -i {slic}.slcio -DoutputFile={out} -d HPS-PhysicsRun2016-v5-3-fieldmap_globalAlign -R 7984
