added condition synchronization of the the archiving add function. This worked fine in 1.6.3 but it doesn't work on 2.3 as it appears that the ArchiveBase.add() function that was synchronized has been overloaded in 2.3 by OpencastArchive.add() for some reason that too has been synchronized even though it mainly calls super.base().
So you had the case of a synchronized function calling a synchronized function!
Hi James, can this issue be resolved?
Done, I didn't noticed it hadn't auto-resolved after the PR merge
