OK, a couple of things. One is, do you have to have 4.2, or can it be
at least 4.2? My reading over at
http://wildfly.org/news/2014/11/20/WildFly82-Final-Released/
indicates that WildFly 8.2 is setup to use Hibernate 4.3.7. If that is acceptable, I think it will make life easiest to use that. I think it is possible to bypass the "installed version" of Hibernate, by deploying your own versions of whatever jar you actually need, into your own app. But it might take more work, and it might require tweaking things (researching, and trying things, etc.). Sorry, but I have not tried anything like that for years.
However, this other
thread https://coderanch.com/t/90896/JBoss/Loading-version-Hibernate-Jboss shows what someone had to do in an old version to get a later hibernate version to work. Nowadays, Jboss 7+ (and Wildfly) have better partitioning of the classpath, as mentioned in
https://docs.jboss.org/author/display/WFLY8/Class+Loading+in+WildFly . So it might not require as much tweaking.
Bottom line, if you really require 4.2 and nothing newer, you can probably make that happen with the latest version of WildFly, and not have to try and change everything in the server to do it.
As an aside, the Oracle
Java EE folks also offer "JPA" which can use Hibernate as its backing (or any other implementation). But, it sounds like you have very specific requirements, here, including Envers.
