[jira] Created: (QPID-3043) If a new session is created during
failover, but before 'resume' is completed, the new session gets reattached
again.
If a new session is created during failover, but before 'resume' is completed, the new session gets reattached again.
---------------------------------------------------------------------------------------------------------------------
Key: QPID-3043
URL: https://issues.apache.org/jira/browse/QPID-3043
Project: Qpid
Issue Type: Bug
Affects Versions: 0.8, 0.7, 0.6
Reporter: Rajith Attapattu
Assignee: Rajith Attapattu
Fix For: Future
This bug was discovered while investigating QPID-2994
There exists a race condition, where if a session is created (after the connection is setup and is marked OPEN) but before the resume method (in Connection.java) is called, it results in the new session being reattached again. This could result in unnecessary duplication of messages.

Andrew Kennedy commented on QPID-3043:
--------------------------------------
The " connectionLost" field is scoped as "private static", so it is shared among all connections on the same JVM. This will lead to undesirable behaviour if only one of those connections is lost, and should probably be instance local. instead.

----------------------------------------
Fixed the error. I had accidentally marked the connectionLost variable as static.
