> Key: WW-4408
> URL: https://issues.apache.org/jira/browse/WW-4408
> Project: Struts 2
> Issue Type: Bug
> Components: Core Actions
> Affects Versions: 2.3.18
> Reporter: Christoph Nenning
> Assignee: Lukasz Lenart
> Priority: Minor
> Labels: session
> Fix For: 2.3.18
>
>
> Since 2.3.18 it happens that I get an NPE when accessing ActionContext.getContext().getSession().
> When i log the Session Map it is printed as "{}" but when calling get() on it, an NPE is thrown. So it is kind of null but not really null ?
> Seems to happen only when no HttpSession is present. The NPE is wrapped in a lot of RuntimeExceptions:
