I am a bit confused. Which platform is broken? Does it work on MacOSX?

I didn't solve the problem, but I managed to get PayPal working by
using my own code with a plain Java URLConnection instead of
WOHTTPConnection.
I still don't know why WOHTTPConnection doesn't work. I've carefully
studied the docs, and I believe it is a bug in WebObject 5.4. Moving
our production server to Java 1.6 is not an option...
Note that the NPE in setHeaders below is not the same place where I
get a NPE. Something is seriously broken.
Thanks anyway.

Similar problem here. That code runs on two machines but not on a
third. We have WO in the apps bundle.
Runs on machine one using Java 1.5/MacOSX, machine two 1.6/Linux,
not on machine three with 1.5/Linux.

I'm trying to get WOPayPal working in WO 5.4, and I've narrowed
down to a problem in readResponse(). Below is some sample code I
am using to fetch a page from my own web server, and it fails on
that as well.
I anybody using WOHTTPConnection.readResponse() ? What am I doing
wrong?
I'm running on 10.5.1 client (same happens on server) with WO 5.4
and a 5.4-specific version of WOnder from late December. It does
the same with last night's build of the 5.4 WOnder.
