> The problem appears in version 6 and in revision 1495454. I attached
> a one-line patch that fixes it.
> In method "SlingServletResolver.activate", the loop over
> "executionPaths" should break immediately after "hasRoot" is set to
> "true". All the iterations after "hasRoot" is set to "true" do not
> perform any useful work, at best they just set "hasRoot" again to
> "true".
> Method "isLive" in class "ResourceResolverContext" has a similar loop
> (over "dynamicProviders"), and this loop breaks immediately after
> "result" is set to "false", just like in the proposed patch. Other
> methods (e.g., "FactoryPreconditions.checkPreconditions",
> "JspUtil.checkAttributes", "EclipseJavaCompiler.compile",
> "SecondPassVisitor.appendPageDirective") also have similar loops with
> similar breaks, just like in the proposed patch.
