This was a basic oversight on my part pointed out by Karl, to whom I'm
extremely grateful. The issue was that the bundle in question did not import
android.util and hence was throwing the error.
I was somewhat confused by the message in the logs:
04-30 15:12:45.557: WARN/System.err(19276): Problem creating boot delegation
class loader: java.lang.reflect.InvocationTargetException
which was generated by ModuleImpl (I think). Since this isn't actually a
problem on Android (in fact, its specifically code for), perhaps this should
be changed to an INFO rather than a warning, or even swallowed ?
Thanks
Bruce
