Class org/xml/sax/InputSource violates loader constraints

[Atherton Richard - Z9V]

I am using the Ant Junit task, running a single suite using the textui. Has
anybody come across the following when using the Ant Junit task? Either the
Ant or the JUnit class loader seems to be complaining about the InputSource
class inside 'xerces.jar'. (We get the problem when using the JUnit Swing
GUI outside of Ant, which has a dynamic class loader).

Cheers,
Richard.
