--------------------------------------------------------
Key: NXP-7326
URL: https://jira.nuxeo.com/browse/NXP-7326
Project: Nuxeo Enterprise Platform
Issue Type: Bug
Components: Core
Affects Versions: 5.4.1
Reporter: Thierry Martins
Assignee: Bogdan Stefanescu
Priority: Major
Fix For: 5.4.3
During performance test run with funkload, some errors occurs related to the
usage of the LoginStack.
It seems concurrent threads are using the same LoginStack, which raises
exception in the login module.
Example:
- At logout:
{noformat}
ERROR [NuxeoAuthenticationFilter] Unable to logout
java.lang.NullPointerException
