Session invalidation in Development Stage causes error in OpenWebBeans

I have a logout method, shown below:

public String logout() {
final FacesContext fc = FacesContext.getCurrentInstance();
final ExternalContext externalContext = fc.getExternalContext();
try

{ externalContext.invalidateSession(); externalContext.redirect("http://www.google.nl"); }

catch (IOException e)

{ log.error("Error redirecting after logout", e); }

finally

{ fc.responseComplete(); }

return null;
}

When I invoke this method, I get the following Exception from OpenWebBeans:

This happens because the DebugPhaseListener starts visiting the tree and, in the process, needs to resolve a value expression, which points to an OWB session bean.

It only happens when the DebugPhaseListener is installed. In production mode everything is fine.
