TomEE Stable and OpenJDK

[f***@rohde-schwarz.com]

Hello everyone,



we are currently using TomEE 1.7.4 and started to discuss an upgrade to the latest version.



Questions (spawned by the TomEE Wikipedia article) arose as to which one is currently the stable (production) release of TomEE: Is it 1.7.5 (as Wikipedia suggests) or the 7.0.4 (as tomee.apache.org suggest) or even 7.0.5 which we have found on a JIRA release notes page?



Another important question we were discussing: Can TomEE run on the OpenJDK JVM without issues or is it necessary to run it on an Oracle JVM? I have read that they are essentially the same, which doesn’t necessarily mean the JDK/JREs are interchangeable, or are they?



Thanks in advance for your answers!



All the best,

Fabian Richter

Hi Fabian,

We're using OpenJDK & TomEE on many prod systems, so I'd say it's good
to go in that sense.

The 1.7.5 branch is the EE6 only version, of which the webprofile is
certified.

The 7.x branch is EE7 compatible, but not certified due only to
licensing issues - It's still very stable and used on many prod systems.

The 8.x branch that will soon be available is EE8 compatible.

Hope that helps,

Andy Gumbrecht.

1.7.5 for the 1 branch and 7.0.4 for the last one

you can refer to http://tomee.apache.org/download-ng.html to know which one
you can pick

Both work well.

I think what the download page fails to communicate is which EE level it addresses.

We should probably split this into different areas on the download page.

To clarify this

TomEE-1.7.x adresses the JavaEE 6 specifications, with minimum requirement Java7 (up to Java8)
TomEE-7.0.x adresses JavaEE 7, with minimum Java7, soon up to Java11 (7.0.5 in preparation right now)
TomEE-7.1.x (wip) will address JavaEE7 + MicroProfile 1.3, with minimum Java8
TomEE-8.0.x (wip) will address JavaEE8 (+ MicroProfile 1.0) with minimum Java8

ATTENTION: we switched the maven groupId from org.apache.openejb.* in TomEE-1.7.x and before to now org.apache.tomee.
So in case you want to update, just change the groupId. All the rest remained the same.

Fabian, I hope I did cover what you were looking for.

TomEE-8.0.x (wip) will address JavaEE8 + MicroProfile 1.0 with minimum Java8

Thanks for that clarification. It may seem obvious to people in the know, but
it is interesting to see a statement on the upper bound of supported JDK/JRE
version, as well as the lower bound. In addition to the supported Java EE
version range, for the major Tomee versions.

Now, just to be explicit here: Apart from EE certification, does the Tomee
community consider OpenJDK on equal footing to OracleJDK when it comes to Tomee
deployment? Is there any important reason not to recommend OpenJDK over, or at
least on par with, OracleJDK?

I'm asking because I still encounter a bit of hesitation towards migrating from
OracleJDK to OpenJDK. It would be helpful if open source projects such as Tomee
made a clear stance on OpenJDK.

BTW, I also run Tomee 7.x on OpenJDK 8, and have not found any issues compared
to OracleJDK. So, now we know there are more than one application deployed on
Tomee and OpenJDK. :)

[Mark Struberg]

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.

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.

8 will, 7.1 is still being discussed AFAIK

The side note is you can import most of mp spec as any lib in any tomee
distro since they never really depends on the container and rely - as any
spec should - on cdi IoC for the wiring.

Hello Romain and Mark,

If I have understood you well, TomEE 8 will address µProfile 1.3 since its first version.

But what about my first question regarding 7.0.5 ?

Best Regards.

Exact dates are hard to provide. As a rough idea, we'll need a OpenJPA
release, and I think Mark is kicking that off soon, and then I think we're
probably good to go. The TomEE release can take a week or to, depending on
any issues that crop up, and allowing enough time to vote.

Hope that is some help.

i also use OpenJDK on CentOS without problem.  I thought OpenJDK was
blessed by Oracle.  I also remember reading that OpenJDK code is used
inside Oracle JDK, Oracle one just has some extra stuff like JavaFX etc
