The second part of your comment doesn't make sense.
I think you are confusing explicit exports (named packages)
with the "exportAll" behaviour (packages are discovered from a scan of the deployment
classpath).

It is clearly trying to load to resource from the classloader and not finding it:

Like I said earlier, hack the policy to turn off the blacklisting and caching,
but this is clearly irrelevant if it can't find the resource in the first place.

The code to find the resource is:


  | 
  |    @Override
  |    public URL getResource(String path)
  |    {
  |       VirtualFile child = findChild(path);
  |       if (child != null)
  |       {
  |          try
  |          {
  |             return child.toURL();
  |          }
  |          catch (Exception ignored)
  |          {
  |             log.trace("Error determining URL for " + child, ignored);
  |             return null;
  |          }
  |       }
  |       return null;
  |    }
  | 
  |    /**
  |     * Find a child from a path
  |     * 
  |     * @param path the path
  |     * @return the child if found in the roots
  |     */
  |    protected VirtualFile findChild(String path)
  |    {
  |       for (VirtualFile root : roots)
  |       {
  |          try
  |          {
  |             return root.findChild(path);
  |          }
  |          catch (Exception ignored)
  |          {
  |             // not found
  |          }
  |       }
  |       return null;
  |    }
  | 

with the "roots" coming from the determineAllPackages() for "exportAll",
you can see this result in the filter of logging above.
