I use Wildfly 8.2-Final, got these problems:
If config setMaxInactiveInterval(2^31/1000+1) in session, this session will quickly destroy. I think It is overflow of integer.
In bumpTimeout, 1000 should be 1000L.

Also after config setMaxInactiveInterval(60) in sessionCreated, set setMaxInactiveInterval(0) is not effect, session will be timeout in 60 seconds.

Wildflay 8.1-Final is OK.
