Calculating diffs causes JDOMParseException

[binfalse]

When triggering the diff computation at the /diff/service/trigger endpoint of https://github.com/SemsProject/masymos-diff-rest many of the tasks fail with

throwing org.jdom2.input.JDOMParseException: Error in building: FWK005 parse may not be called while parsing

Not sure what's the problem -- maybe jdom2 is not thread-safe?

The "good" thing is, that you can call the trigger multiple times and it will fail on different documents... Thus, we can work around that by triggering a few more times.. ;-)
