Karaf 4.1 and JDK9

Hi,

got a question regarding Karaf 4.1 and JDK9 compatibility.
I've seen we had numerous issues regarding JDK9 for Karaf 4.1.
Is it our goal to have Karaf 4.1 runnable with JDK9?
If so, the ops4j community just came across some major drawbacks.

First it just seemed like we just need to bump the version for ASM in
Pax-Web [1][2][3] and everything is smooth, but it's not.

It turned out we also need another upgrade for ASM 6 in Aries [4], but
again this isn't the only thing.

It turns out, Jetty 9.3.x isn't compatible with JDK9, so an upgrade to
Jetty 9.4 might be needed.
Again this turns out to be more complex then first anticipated.
As it turns out, neither Jetty 9.3 nor 9.4 are ready to go for ASM 6, but
still rely on version 5 [5].
Not to speak of the need to bump Pax-Web to version 6.1 for using Jetty
9.4.

So how do we handle JDK9 for Karaf 4.1?
Is it our main goal to support JDK9 from head start?
If the answer is yes, we need to do a lot more then what we've done so far.
Just to mention one thing that needs to be done instantly, have a build
which uses JDK9 to run our tests. That should already cover most of the
issues we came across.
Also I would like to hold back the release for 4.1 for a while to make sure
we have all project we or our users depend on straightened for JDK9.


regards, Achim

+1.

It looks like we'll have a lot of work to do to have a full JDK9 support.

Hi Achim,

I plan to release Karaf 4.1.0 by the end of this week as it is, with 
full JDK8 support, and JDK9 support preview (not fully tested).

I would consider the full JDK9 support for Karaf 4.2. I'm pretty sure 
that other projects (Pax Web as you said, but also Aries Proxy) are not 
fully ready, so, it's not really possible to announce a full JDK9 support.

My plan is to create the karaf-4.1.x branch tomorrow, and then, prepare 
the full JDK9 support on master.

Thoughts ?

JB

There are way too many unready dependencies, agreed. Making JDK 9 a goal
for 4.2 sounds reasonable.

Re: Karaf 4.1 and JDK9

Posted by Achim Nierbeck <bc...@googlemail.com>.
Ok, I'm rather fine with those perceptions,
In that case I'd revert the ASM 6.0 ALPHA dependencies for Pax-Web 6.0.1,
they're ALPHA right :)
and we will just call [1], as non fixable for 4.1, and post-pone this to a
4.2, with support for a Pax-Web 6.1.
In that case I'll just create a new 6.0.x branch for Pax-Web and will
change master to 6.1
This way a soon to be available 4.2 (master) SNAPSHOT version will take
care of it.
Any objections?

Agreed.
Especially, things are still moving in the JDK land and we may expect
additional breakages, so I would not hold Karaf 4.1 for that.
We can't really claim to support Java 9 support before it's even released
;-)

Hi Achim,

For Karaf 4.1, the purpose is not to fully support JDK9 but to start the 
required improvements.

I plan to release Karaf 4.1.0 by the end of this week as it is, with 
full JDK8 support, and JDK9 support preview (not fully tested).

I would consider the full JDK9 support for Karaf 4.2. I'm pretty sure

fully ready, so, it's not really possible to announce a full JDK9 support.

My plan is to create the karaf-4.1.x branch tomorrow, and then, prepare 
the full JDK9 support on master.

Thoughts ?
