Concurrent checkin in Jackrabbit

["De Georges, Adrien" <Ad...@experian.com>]

Hello everyone,

I have a question about how JackRabbit is managing concurrent checkin. I am quite sure that no method is synchronized in VersionManager source code.
I am experiencing a strange scenario where a branch is created during a checkin (I mean the version of the checkin is X.X.X and not just X.X). I am thinking about 2 different sessions (in XA transactions) accessing to the same node for checkin almost at the same time. The first one calls checkin on the node. The second one call checkin and the version name is calculated. And the VersionManager appends a ".O" at the end of the version name because the predecessor already have a successor.
Is it the normal behaviour? Does somebody already experience this scenario?
Thanks a lot

Regards,
Adrien
