Hi,
For the record I've created JCR-790 and attached the thread dump and
Marcel's lock explanation.
Miro's workaround of putting an additional level of synchronization
on all write operations on the repository is not quite suitable in
our case. Not only because of the performance hit, but we will soon
need to load-balance the backoffice application too, and implementing
an additional cross-application synchronization mechanism does not
really make sense.
As for this specific deadlock, it seems that it comes from the fact
that a new versionable node is being initialized while another one is
being saved.
I suppose it may not be a good idea to fix this with a hack if a
bigger redesign is needed. However if that redesign is only coming in
several months, a little hack might be ok for a while ;-)
It really depends on the frequency of occurrence, so we'll see how it
goes for us and if we can gather more info.
Thanks for the quick answers!
