Subject: [PATCH] WrappedFilterConfig: Fix 'unchecked or unsafe operations'
 warning

- Use Collections.emptyEnumeration() which is available in Java 7,
  rather than the Collections.enumeration(Collections.emptyList())
  workaround that was used for Java 6 compatibility.

- Add type specification to prevent "unchecked conversion" warning.

- Remove @Suppress annotations that are no longer necessary.
