Subject RE: TomEE Stable and OpenJDK
Date Mon, 14 May 2018 12:16:39 GMT
Hello Mark,

Thanks a lot for sharing the TomEE roadmap.

My main concerns about TomEE are:
    -  java 9 and above support (java 10 and 11)
    - JavaEE 8 specification support
    - µProfile follow up: no TomEE µProfile released yet whereas others exist today like
Payara micro, Wildfly Swarm for example.

So first, java 9 and above support: when you say 7.0.5 in preparation right now, could you
provide us please a release date ?
Second, I have another question: TomEE 7.1.x will address µProfile 1.3, right ? So why, TomEE
8.x won't address µProfile 1.3 at starting point ?

Best regards.

I'm running it in production with OpenJDK.

Actually whenever you have some RHEL server then you will run on OpenJDK.
So those days everything which is in the Linux server area will almost certainly run perfectly
fine on OpenJDK.
