Update Datamapper for JRuby exception.
Ignore JRuby and Datamapper issues.
Datamapper has been EOL for a couple years and is failing on latest JRuby. This is likely a problem we don’t need to worry about as DM support or the latest JRuby is not our main concern at this point.
Don’t exclude the test, just allow it to fail.
