[jira] [Created] (WW-4715) Scope interceptor always resets because of org.apache.struts2.dispatcher.HttpParameters

Greg Baker created WW-4715:

             Summary: Scope interceptor always resets because of org.apache.struts2.dispatcher.HttpParameters
                 Key: WW-4715
                 URL: https://issues.apache.org/jira/browse/WW-4715
             Project: Struts 2
          Issue Type: Bug
          Components: Core Interceptors
    Affects Versions: 2.5.5
            Reporter: Greg Baker


Line 302 of org.apache.struts2.interceptor.ScopeInterceptor performs a not-null check to see if a session reset parameter exists by calling com.opensymphony.xwork2.ActionContext.getParameters().get(...).

The return type of getParameters() is org.apache.struts2.dispatcher.HttpParameters, and HttpParamters.get() never returns null on a missing parameter, causing the not-null check to always evaluate to true.

This breaks the interceptor by short circuiting the scoped variable injection.
