>             Project: WildFly
>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>          Components: Web (Undertow)
>    Affects Versions: 8.0.0.CR1
>         Environment: windows. firefox
>            Reporter: Leos Literak
>            Assignee: Stuart Douglas
>            Priority: Minor

> It occurs to me quite regularly:
> I have servlet, construct some GET URL and find bug. So I fix it, redeploy my war application and press reload in firefox. But WildFly fails with NPE. If I reload the page again, then it works.
