Hi [~tdomok],
Could you please verify if we need backport to older branches (3.3, 3.2, 3.1)? 
Thanks.

> AutoCreatedQueueTemplate calculates wrong wildcard level so a *root.** wildcard won't match for a *root.queue* for example.
>  
> Here the min should be min(queuePathMaxIndex, MAX_WILDCARD_LEVEL), instead of this:
> {code:java}
> int supportedWildcardLevel = Math.min(queuePathMaxIndex - 1,
>         MAX_WILDCARD_LEVEL);
> {code}
> Test code to validate the fix:
> {code:java}
>   @Test
>   public void testWildcardAfterRoot() {
>     conf.set(getTemplateKey("root.*", "acl_submit_applications"), "user");
>     AutoCreatedQueueTemplate template =
>         new AutoCreatedQueueTemplate(conf, new QueuePath("root.a"));
>     template.setTemplateEntriesForChild(conf, "root.a");
>     Assert.assertEquals("acl_submit_applications is set", "user",
>         template.getTemplateProperties().get("acl_submit_applications"));
>   }
>  {code}
