Description

I'm not sure whether to classify this as a bug or an improvment so please reassign at will.

I'm using version 2.6.3 of Artemis and trying to set up a divert from one queue to another using an xpath filter on the message content. Unfortunately this doesn't work as my XML Test messages are not getting diverted but stay in the incoming queue.

So, Justin Bertram pointed me to https://github.com/apache/activemq-artemis/blob/master/artemis-server/src/main/java/org/apache/activemq/artemis/core/filter/impl/FilterImpl.java#L210
writing this feature is not implemented yet.

Unfortunately this also fails silently (no log message, no exception) and is not documented anywhere so it was a real headache to debug.

Is there another way to do it? If not, is this a bug or a Feature/Improvement? (I think this was already working in AktiveMQ 5.something)

My adresses in broker.xml look like this     

<addresses>          
...
DLQ and ExpiryQueue
...
<address name="Incoming">            
  <anycast>                
    <queue name="Incoming" />            
  </anycast>          
</address>        
<address name="XMLMessages">             
  <anycast>               
    <queue name="XMLMessages" />            
  </anycast>         
</address>        
</addresses> 

My divert:

<diverts>   
  <divert name="xmldivert"> 
    <address>Incoming</address> 
    <forwarding-address>XMLMessages</forwarding-address>                     
    <filter string="XPATH '//ContractedTimeTableMsg/Message'"/>      
    <exclusive>true</exclusive>   
  </divert>         
</diverts>

My XML

<ContractedTimeTableMsg> 
  <Message type="123"> 
  </Message>
</ContractedTimeTableMsg> 

I'm using Java 8 and a standalone installation of Artemis.
Xalan is on the classpath, I tried version Xalan 2.6 and v2.7.
