[Geoserver-devel] Upgrading to JDK 6: has the time come?

GeoServer GeoServer Developer
1

Hi,
first off, sorry for cross posting on GeoTools and GeoServer devel,
the topic is however
of interest of both communities.

I'm wondering if times are finally mature to switch GeoTolols and
GeoServer trunk to JDK 1.6 as
the minimum requirement (just trunk though).

The rationale being that J2EE 6 has been out a while, JDK 1.5 is end of life
and hard to grab, and JDK 7 is going to be released shortly (July I think).

Not switching 2.1.x series to JDK 6 will give people stuck on JDK 1.5 some
6-12 months more of support.

Also, according to this, jdk 6 will reach its end of life next year
already, meaning
we will have only 1 year of that jdk in supported state before its end of life
(assuming we switch soon):

Opinions?

Cheers
Andrea

Yeah, I would be ok with requiring java 6 for gt 8.1 / gs 2.2. Part of my motivation is that using java 5 on a mac has become increasingly difficult in recent releases of OSX.

However that said, i think past getting developer agreement for the change we really should try to best we can poll the user community. I am thinking maybe we can set up one of those polls on the website to allow people to input their choice? And then try to generate as much traffic to it as possible via blog, email lists, twitter, etc…

Just a thought.

This had my support last time; and does so again now.

As per the osgi thread I have been looking into what is needed to support geotools on andriod - one of the items involves use of the Java 6 Service Loader (rather than ServiceRegistery).

uDig has already transitioned to a Java 6 only project, the release of GeoTools 8 is a year off (given our usual release cycle) providing some time before the effect of us yanking Java 6 support is felt in a stable release.

+1 on making a pool.
At the same time, given the EOL of Java 6 in one year, I'm wondering if we're
actually left with much of a choice

Ah hem, freudian slip I presume... A poll of course :slight_smile:

+1 from me (as far as I know we were holding at 1.5 solely for GeoServer).

Hello all,

We set up a poll for this last year. Here is the page:
http://micropoll.com/t/KEJiqZBItn

I guess we make a new one that talks both about GeoServer and GeoTools?
Or two separate ones.
Then reset, have the media machine (twitter, blog, mailing list) do its job and
wait for the fruits :slight_smile:

Cheers
Andrea

So all together or separate ? (We could have a poll).

Aaagh, meta poll!

Let me make the call: separate.
If anything things this is really a big mistake and we should do them together
let's talk about it :-p
