feeding an empty Atom entry file to CollectionAPI.post results in org.apache.abdera.parser.ParseException: java.lang.ArrayIndexOutOfBoundsException

[pdurbin]

If atom-entry-empty.xml is an empty file (i.e. touch atom-entry-empty.xml to create it) and I try to feed it into CollectionAPI.post like this...

curl -s --insecure --data-binary @scripts/api/data-deposit/data/atom-entry-empty.xml -H 'Content-Type: application/atom+xml' https://pete:pete@localhost:8181/dvn/api/data-deposit/v1/swordv2/collection/dataverse/peteTop

... I get the exception below. Perhaps a try/catch could be added?

Here's the relevant line: https://github.com/swordapp/JavaServer2.0/blob/sword2-server-1.0/src/main/java/org/swordapp/server/SwordAPIEndpoint.java#L355

The Java SWORD library is upstream of me but here's where I'm tracking this issue: IQSS/dataverse#893

A related bug is that we get org.apache.abdera.parser.ParseException when trying to create a SWORD entry with some XML that contains an invisible character:

https://github.com/IQSS/dataverse/blob/master/scripts/api/data-deposit/data/atom-entry-study-894-invisible-character.xml

However, I was able to catch org.apache.abdera.parser.ParseException in my code
