--------------------------------
Summary: NPE in
org.apache.webbeans.servlet.WebBeansConfigurationListener.ensureRequestScope()
Key: OWB-920
URL: https://issues.apache.org/jira/browse/OWB-920
Project: OpenWebBeans
Issue Type: Bug
Components: Context and Scopes
Affects Versions: 1.2.1
Reporter: Joe Bergmark
Assignee: Joe Bergmark
Priority: Minor
It appears that WebBeansConfigurationListener.ensureRequestScope() is trying to
make sure the requestScope is active on the thread. Unfortunately, I believe
in many cases when it isn't active, the line below with lead to a NPE:
if
(!this.lifeCycle.getContextService().getCurrentContext(RequestScoped.class).isActive())
getCurrentContext can return null if this was called on a http request thread
(for example a thread invalidating sessions), leading to an NPE when isActive()
is called.
I believe a simple fix would be to ensure the context isn't null and if it
isn't null ensure it is also active.
A sample stack trace below:
