<br>Hi guys,<br><br>Having briefly investigated<span> </span><a href="https://issues.jboss.org/browse/ISPN-2314" target="_blank">https://issues.jboss.org/browse/ISPN-2314</a>, I consider the fix (<a href="https://github.com/infinispan/infinispan/pull/1318" target="_blank">https://github.com/infinispan/infinispan/pull/1318</a>) to be rather fishy.<br>
<br>Sure it works, but it masks the fact that the order in which things are started has changed (This IMO seems to be the result of<span> </span><a href="http://issues.jboss.org/browse/ISPN-2256" target="_blank">http://issues.jboss.org/browse/ISPN-2256</a>).<span> </span><br>
<br>Not only that, but the fact that you have to modify both the component registry and the configuration makes me think that there're situations where the configuration changes are applied, and others where it's not (hence why you have to change the component registry).<br>
<br>So, can we please stop and try to understand what really is happening here? I was expecting Mircea to have a look into a fix for this since it looks related to cache start order.<br><br>Personally, I don't really see why the lifecycle manager has to mess up with the component registry. Changes to the configuration were 'enough' (until 2256) and I don't see why that should change.<br>

<br>On the other hand, I'm not sure why would the interceptor chain exist during restart but not during start. AFAIK it's a volatile component, so it should be removed during shutdown.<br><br>Cheers<br>Dan<br><br>
