Re: [wildfly-dev] Using a custom module to preview "next-gen" Hibernate versions on WildFly 9

Could someone explain please, why it's hard to have a deployer just use a different JPA implementor which the user might want to provide?

I'm pretty sure I know how to start a JPA context in plain JavaSE, and don't need to know which implementor version I'm going to use, other than for sake of configuration. The WildFly documentation mentions this property "jboss.as.jpa.providerModule", which sounds great on paper and it would be a nice usability improvement if it would also actually work as it suggests.

There's plenty of evidence on StackOverflow that the current limitations are unexpected. For example, Spring moved to Hibernate 5 and people won't be able to use your stable line of the application server with Spring; I'd hope we could implement a plan to prevent this from happening at the next upgrade cycles.
