Push not working when redeploy on Glassfish 4.1

[ykartal]

Hi,

I'm new to PrimeFaces.
I've worked with Push messages and Charts. Everything seems ok but after redeploy(undeply and deploy) to Glassfish 4.1, Push messages stops working.

If it is application's first deploy, it works.
If I undeploy and deploy, push stops working.
If I undeploy, restart glassfish and deploy, it works.

I try to find problem and noticed that; while glassfish is undeploying the project, the atmosphere jar could not be deleted.
All files are deleted but WEB-INF/lib/atmosphere-2.2.6.jar not.
I also tried to stop atmosphere on undeployment process, but have no success.

Any idea?
