Here is the first problem, when running with importAll=false


  |    public void testExplicitImportGenerateClassInExistingPackage() throws Exception
  |    {
  |       runExplicitImportGenerateClass(EXISTING_PACKAGE, true);
  |    }
  |    
  |    private void runExplicitImportGenerateClass(GeneratedClassInfo info, boolean expectSuccess) throws Exception
  |    {
  |       ClassLoadingMetaDataFactory factory = ClassLoadingMetaDataFactory.getInstance();
  |       String dynamicClassRoot = getDynamicClassRoot();
  |       VFSClassLoaderFactory a = new VFSClassLoaderFactory("a");
  |       a.getRoots().add(getRoot(A.class));
  |       a.getCapabilities().addCapability(factory.createPackage(A.class.getPackage().getName()));
  |       KernelDeployment depA = install(a);
  | 
  |       VFSClassLoaderFactory b = new VFSClassLoaderFactory("b");
  |       b.getRoots().add(getRoot(B.class));
  |       b.getRoots().add(dynamicClassRoot);
  |       b.getCapabilities().addCapability(factory.createPackage(B.class.getPackage().getName()));
  |       b.getRequirements().addRequirement(factory.createRequirePackage(A.class.getPackage().getName()));
  |       KernelDeployment depB = install(b);
  | 
  |       ...
  |    }
  | 

When deploying this, I get the following error

  | 1218 ERROR [AbstractKernelController] Error resolving dependencies for Installed: name=b:0.0.0$MODULE state=Start
  | java.lang.IllegalStateException: VFSClassLoaderPolicyModule b:0.0.0 cannot be added because it is exports package newpackage which conflicts

I was not really expecting problems at this stage, I was writing this test to investigate if we would need a GlobalRequirementsProvider. The package "newpackage", mentioned in the trace, is one of the global capabilities. Can really 2 loaders with importAll=false not export the same package, or have I done something wrong?
