Objet : Re: [p2-dev] Error in the p2 workspace;
org.eclipse.equinox.p2.jarprocessor missing export
There is a little bit about this in the help:
http://help.eclipse.org/helios/index.jsp?topic=/org.eclipse.platform.doc.isv/guide/ant_developing.htm
Essentially,
the classes that are part of the ant tasks should not be visible to the osgi
class loader. This is because we need need the classes to get loaded by
the ant classloaders, otherwise at runtime you can get ClassCastExceptions.
It can be very
confusing and frustrating trying to debug a problem and getting exceptions
casting org.apache.tools.ant.Project to org.apache.tools.ant.Project. :)

This is PDE acting up, the .ant packages
should not be exported since they are not meant to be used by any other type
and just be made available through the Ant tasks.
