link:[Issue 2702]:
Fix race condition in change merge queue when using Cherry-Pick submit
There was a race in the merge queue between changes submitted via
the UI, and merges scheduled by the background merge queue reload.
This resulted in multiple submit actions being scheduled, leading
to corrupt changes.
Execute cherry-pick submit DML operations in a database transaction
boundaries. In combination with implemented transaction management
for Jdbc dialects it solves the problem recovering from collisions
between interactive actions and background jobs.
* In gwtorm the LIMIT clause was only honored when followed by a
constant integer.
When followed by a placeholder "?" it wasn't included in the generated database
query. This caused poor performance when moving to the next change page for very
big projects.
* Fix sporadic SSHD handshake failures
== Updates
* gwtorm is updated to 1.7.1
* sshd is updated to 0.11.1-atlassian-1
