Did you try turning off the "Reload classes on each run" checkbox in the
Junit gui? If this option is on, Junit uses its own classloader, which
often causes problems. When turned off, the system classloader is used and
the behavior should be the same as when running the tests manually.

Thema: RE: ClassCastException with rc4
Thanks,
I've been over my classpath again and again but can't find any duplicates.
It is a problem with multiple class loaders but only when I use the Junit
gui to run my tests. If I run my test classes manually (without Junit)
then
it works ok. Frustrating though.

Hi,
Could you make sure that you do not have several times the same jar file
in your classpath.
A few times ago I had a similar problem where an exception stated to me
wrongly that a class did not implement an interface. It was a problem
with multiple class loaders.
