[Webtest] <setproxy ... /> fails inside <then> ?

[George Policello]

The following gets the page just fine but it fails on the
   <then> <setproxy proxyhost=3D'' />
with
Unexpected exception caught: org.apache.tools.ant.BuildException

The stack trace did not help much.

GOAL:
The goal is to get passed any URL for which the <invoke ... /> fails
for a reason other than those covered by the <config ...><option>
capabilities.
For example, Timeout, Connection, or
  "Unexpected exception caught: java.net.SocketException"
errors.

BACKGROUND:
All the <options> mentioned in the manual text
  http://webtest.canoo.com/webtest/manual/option.html=20
are set to "false".

Why?
The <setproxy proxyhost=3D'' /> is needed before moving on or the
next step gets an UnknownHostException.

Basically, used example 2 of ifStep as an example
  http://webtest.canoo.com/webtest/manual/ifStep.html

Has anyone seen something similar before? Any suggestions would be
welcome.
Even a different way to deal with the Goal instead of the existing code.

Thanks,
