docs: Retrieve a TraceNLS instance for the specified ResourceBundle, after
  first calculating the class of the caller via a stack walk (a direct call
  passing in the class is preferred).
  
  @param bundleName
  the package-qualified name of the ResourceBundle. The caller
  MUST guarantee that this is not null.
  <p>
  @return a TraceNLS object. Null is never returned.
  
  @deprecated Use the signature that includes the class object instead
