Call.getOutputParams() does not work!

Title: Call.getOutputParams() does not work!

I am now using Axis 1.1 RC2. The Call.getOutputParams()
always returns an empty Map.
I have checked the source, the Call.invoke has following code:
        result = outParams.remove(qname);
It looks like, the invoke() will remove the output when it
returns a paramter. Is it a bug? because this way,
the Call.getOutputParams() becomes useless!!
and this method works good in Axis 1.0.
Who can give me the light?
Thanks
