[wildfly-dev] WildFly's transaction subsystem needs a diet (too much Artemis!)

[Tristan Tarrant]

Hi all,

ever since wildfly-core was conceived I've wanted to deliver an 
Infinispan Server distribution based on it using a feature-pack. 
Unfortunately this has not been possible because we depend on two 
subsystems which are not part of core: datasource and transactions.
Our current approach, therefore,  implements a feature pack based on the 
full wildfly. We then use some scripts to build a tree of module 
dependencies, we identify unused modules and we trim them from the final 
distribution.
Unfortunately this trimming is not effective as it could be because of 
the org.jboss.as.transactions module which pulls in a ton of 
nono-optional dependencies. You can find the dependency tree at the end 
of this e-mail.
In particular the culprit seems to be org.jboss.jts which depends on 
org.apache.activemq.artemis which in turn is a kitchen-sink of artemis-* 
dependencies. [1]

I guess Narayana is only really interested in Artemis' journal, so the 
laziness of the artemis module is particularly painful.

Can the artemis-journal/artemis-native jars be split out into their own 
independent module ? This might be harder than it seems as the journal 
classes seem to depend on artemis-server, so deeper surgery is needed.
