We've been aware of this issue for a while. Unfortunately, the locking
implementation is pretty hard to disentangle, and we haven't been able
to come up with a fix. However, we have been able to work around it by
adding an extra level of synchronisation in our own application that
ensures only one simultaneous versioning operation can occur. I guess
it depends how big a hit this would be as to whether it would be a
suitable solution for anyone else.

Hi,

Seems like another case of the age-old JCR-18 issue with concurrent
versioning. Both of the updates contain some versioning operations,
and since concurrent versioning is at the moment still a rather
dangerous sport, I'm not surprised if bad things like a deadlock can
occur.

Any contributions in further diagnosing and resolving the concurrent
versioning issues would be very much appreciated!

BR,

Jukka Zitting
