HttpUnit not returning all headers

I am having a problem  testing my web app. Looks like the problem is
that httpunit is not returning all the http headers received.

I am using httpunit 1.6.2 and JDK 1.5.0_06 on Linux.

Is this a known bug, or is there some flag that needs to be set to get
all headers?

I have a very simple test that fails:

WebResponse wr = wc.getResponse("http://127.0.0.1/sup/review/");
System.out.println("wr: " + wr);

Headers as returned by HttpUnit:

wr: HttpWebResponse [url=http://127.0.0.1/sup/review/; headers=
