Yes, direct awt support was dropped in the transition.

The problem is that the classloader is, rightly, denying access to the
package.  I'm not sure if this will actually work, but if you add
something like the following to ants/core/AppBooster.java it should tell
the class loader to allow access:

  flow.addSystemPackage("java.awt");
  flow.addSystemPackage("java.awt.event");
  flow.addSystemPackage("java.awt.<other subpackages>");
