Invalidations on locks not received when running a vcs client session
---------------------------------------------------------------------
Key: NXP-5808
URL: https://jira.nuxeo.org/browse/NXP-5808
Project: Nuxeo Enterprise Platform
Issue Type: Bug
Affects Versions: 5.4
Reporter: Stéphane Lacoin
Priority: Major
In this condition
* two VCS servers in a cluster : ServerA and ServerB
* two VCS client, each connected to one distinct server (ClientA on ServerA and
ClientB on ServerB)
* clients have a session dedicated to the thread UI used mainly for retrieving
documents
* clients execute lock operation on distinct sessions server side by sending an
operation
* clients are polling the session dedicated to the thread UI every 10 seconds
When ClientA locks a document, ServerA is registering a cluster invalidation :

NX_CLUSTER_INVAL('6e6fbc9d-55f6-46b2-8ed6-68ab1d71dacc', 'locks', 1)
Then ServerB received the invalidation and propagated to all local sessions
while processing the hearbeat

The invalidation was received by ClientB while saving a session as a cache
invalidation and was not relayed as a core event.
