JabRef version 5.0-alpha on Mac OS X 10.15 x86_64

• I have tested the latest development version from http://builds.jabref.org/master/ and the problem persists

When trying to lookup a DOI for an entry, I get the error "An I/O exception occurred". The answer from api.crossref.org says: "Parameter query.title has been deprecated. Please use query.bibliographic instead. See https://status.crossref.org/incidents/4y45gj63jsp4"

Steps to reproduce the behavior:

1. Open entry without DOI reference
2. Lookup DOI
