Default jsf 2.0 resource lookup fails if resources are present in jar in WEB-INF/lib
------------------------------------------------------------------------------------

                 Key: JBAS-7775
                 URL: https://jira.jboss.org/jira/browse/JBAS-7775
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
    Affects Versions: JBossAS-6.0.0.M2
            Reporter: Johan Kustermans


We have a JSF 2.0 composite component in WEBROOT/resources and at the same time a jar in WEB-INF/lib that has resources under the
META-INF/resources directory. Then a nullpointer is thrown with  the following stacktrace

The error is thrown in the listbindings-method of the ProxyDirContext at the line

while (overlay.hasMore()) {
   Binding pair = overlay.next();
    ...
}

because overlay = null. This part of the code is reached in this case because the presence of the kind of jar mentioned in the beginning of this issue description implies that the overlays member field of the ProxyDirContext is not-null.

A simple check on overlay != null before executing the while loop seems sufficient to resolve the issue.
