    Fundamental class space issue

      Please consider this

      A imports X
      B imports X

      Can X load a class from A or B?
      Can A load a class from B and vice versa?

      https://jira.jboss.org/jira/browse/JBOSGI-142

      This works with Felix, but fails with the MC Framework.

       BundleContext sysContext = framework.getBundleContext();
 Bundle bundleX = sysContext.installBundle(getBundleLocation("jbosgi142-bundleX.jar"));
 bundleX.start();

 String classX = bundleLoadClass(bundleX, BeanX.class);

 Bundle bundleA = sysContext.installBundle(getBundleLocation("jbosgi142-bundleA.jar"));
 bundleA.start();

 String classA = bundleLoadClass(bundleA, BeanA.class);

 Bundle bundleB = sysContext.installBundle(getBundleLocation("jbosgi142-bundleB.jar"));
 bundleB.start();

 String classB = bundleLoadClass(bundleB, BeanB.class);

 assertEquals("BundleA loads BeanB", classB, bundleLoadClass(bundleA, BeanB.class));
 assertEquals("BundleA loads BeanX", classX, bundleLoadClass(bundleA, BeanX.class));

 assertEquals("BundleB loads BeanA", classA, bundleLoadClass(bundleB, BeanA.class));
 assertEquals("BundleB loads BeanX", classX, bundleLoadClass(bundleB, BeanX.class));

 assertEquals("BundleX loads BeanA", classA, bundleLoadClass(bundleX, BeanA.class));
 assertEquals("BundleX loads BeanB", classB, bundleLoadClass(bundleX, BeanB.class));

          bundleA and bundleB do not seem to share the same class space.
