I changed the reset logic such that it resets to the state that it was before the resolve attept.
Instead of always reset to "DESCRIBE".

      // Advance the bundles to stage CLASSLOADER and check at the end
      if (advanceBundlesToClassloader(resolvableBundles) == false)
      {
         resetBundleDeploymentStates(resolvableBundles);
         allResolved = false;
      }


private void resetBundleDeploymentStates(List<OSGiBundleState> resolvableBundles) 
   {
      for (OSGiBundleState bundleState: resolvableBundles)
      {
         DeploymentUnit unit = bundleState.getDeploymentUnit();
         StateTuple stateTuple = unit.removeAttachment(StateTuple.class);
         if (stateTuple != null)
         {
            stateTuple.reset(unit);
         }
      }
   }


The DeploymentMetaData is not available in 6.0.0.M2, so I had to refactor that out into a separate deployer that does a noop in M2.

With the recent change we also get spurious WARN messages

which is because the DynamicClassLoaderPolicyFactory does not create a policy. Not sure how this is suposed to work.
