[Htmlunit-user] awt or swing UI Exception

[Damien T. <D.T...@ka...>]

When trying to run the simplest of HtmlUnit tests using the junit awt
and swing runners I get the following error.=20

I only have reference to commons-logging-1.0.4.jar on my class path.
When I remove it from the class path I get a different error indicating
that it cannot find the logging classes.

Any ideas what could be causing this or how i could ifx it.  Note: the
test works fine when using the text runner.

Thanks
Damien
