Linkage error with Ant classloader

I am Using Ant 1.2 and have the following code

persistor_ = (IObjectPersistor)
Beans.instantiate(this.getClass().getClassLoader(), className);


this seems to be generating an intermittent linkage error and I believe it
is related to the Ant classloader.


java.lang.LinkageError: duplicate class definition:

Any help with this would be appreciated
