[jboss-as7-dev] Netty upgrade for AS7

[Jeff Mesnil]

Hi guys,

This is of interest for infinispan, web & messaging subsystem and the test suite.

As a part of upgrading HornetQ to 2.3.O.BETA1 in AS7[1], we also need to upgrade its dependency to Netty 3.4.5.Final[2].
Inside AS7, the Web subsystem also depends on Netty. Guys, is it ok for you to upgrade to 3.4.5?

Unfortunately, to move from Netty 3.2.x to Netty 3.4.x, we must also change its groupId from org.jboss.netty to io.netty.

If I do that, I can no longer build AS7 test suite because of bad dependencies which requires Netty 3.2.x:

+-org.jboss.as:jboss-as-testsuite:7.2.0.Alpha1-SNAPSHOT
   +-org.jboss.as:jboss-as-build:7.2.0.Alpha1-SNAPSHOT
     +-org.jboss.as:jboss-as-core-model-test:7.2.0.Alpha1-SNAPSHOT
       +-org.jboss.as:jboss-as-model-test:7.2.0.Alpha1-SNAPSHOT
         +-org.sonatype.aether:aether-connector-asynchttpclient:1.13.1
           +-com.ning:async-http-client:1.6.5
             +-org.jboss.netty:netty:3.2.5.Final
and
+-org.jboss.as:jboss-as-testsuite:7.2.0.Alpha1-SNAPSHOT
   +-org.projectodd.stilts:stilts-stomp-client:0.1.26
     +-org.projectodd.stilts:stilts-stomp-api:0.1.26
       +-org.jboss.netty:netty:3.2.1.Final

Since only the test suite depends on Netty 3.2.x, in my PR, I have 2 versions of Netty:
* io.netty Netty 3.4.5.Final => used by AS7 codebase
* org.jboss.netty Netty 3.2.x => used by AS7 test suite

This is ugly but this works...
However, I'd like to reconcile these 2 versions and upgrade everything to 3.4.5.Final

I have submitted patches for Stilts[3] and Aether connector[4] to upgrade their dependencies to Netty 3.4.x (groupId=io.netty).
Until they release new versions of their components, we are stuck with Netty 3.2.x.

Another question is about the recent upgrade to Infinispan 5.2.0.BETA1[5]. When I look at this version's POM[6], it depends on 
Netty 3.4.6.Final. Shouldn't have Netty been updated at the same time than Infinispan?
If that's not required to upgrade a component dependencies when the component is upgraded, I could postpone Netty 3.4.x upgrade. 
However some HornetQ bugs requires this version (e.g. for WebSockets support[7]). I really want to keep the AS7 dependencies in 
sync with the deps of HornetQ that is integrated.

wdyt?
