What is Geode's language level
I'm looking at the source code and I was wondering what is the language
level that Geode is aiming for. Currently it seems compatible with Java
1.6, wondering if that minimum will be raised.

Joao,
You ask a very good question that we contributors need to add to the wiki, as well as some suggestions for easy places for new contributors to start.

What is the best way forward to progress this ask? Via the Geode OSS committee? I vote we should move ASAP.

Re: What is Geode's language level
Posted by Dan Smith <ds...@pivotal.io>.
Hi Lyndon,
Maybe you're getting confused between what language levels geode supports
and what language level geode code is written in? We don't need different
branches to support java 8, java 9, etc. Geode should already work with
later versions of java. If there are issues running on java 8 or 9 those
should just get filed and fixed.
Geode is current written in java 7 so that we can continue to support java
7 users. We may want to drop java 7 at some point to make life better for
geode *developers*, but geode *users* should already be able to use the
latest JVM versions.

Re: What is Geode's language level
Posted by Kirk Lund <ki...@gmail.com>.
The key here is probably to replace the term "customer" with "user". As
long as "users" want or need to use Geode in JDK 1.7 then we need to keep
1.7 in the picture. Users can of course participate in the community, and
it's up to those of us in the community to represent them as best we can.
If you want to propose moving the build to 1.8, then I think you would
simply propose that on the dev@geode email list. Then everyone on the Geode
PMC could discuss it or even vote on it.
Ultimately, it probably comes down to this: if each person in the Geode PMC
group believes that all "users" are ready to leave 1.7 behind and move to
1.8, then they should vote +1, else they should vote -1.
Even though there hasn't been a Geode release yet, we probably have to
assume or at least hope that existing GemFire users will eventually become
Geode users.

Re: What is Geode's language level
Posted by Lyndon Adams <ly...@gmail.com>.
"Customer support" is a paid service, Geode is for all. Geode OSS should sit on the curve of technology evolution and should embrace all advances with velocity. Thus any reference to "customer" should not be a concern for the Geode vision and code base.
The decision of language level should be driven by OSS community and the general Apache minimum supported JVM platform.
Just a penny for my thoughts.

versions of Java 6 and 7 runtimes running in customer sites for sometime...
http://www.oracle.com/technetwork/java/eol-135779.html#java-commercial-offerings
Most application servers still ship with Java 6, don't even fully support
the Java 7 spec, and have opted to start moving directly to Java 8 support,
no double because they are lagging behind and that Java 7 was not really a
huge success.
For the first time ever, the core *Spring Framework* will concurrently
support and run on Java 6, 7, 8, and 9. This is significant because it
allows newer Java features to be used with the core SF based application
while simultaneously preserving compatibility with older runtimes.
Of course, the core *Spring Framework* dwarfs GemFire/Geode installations
several orders of magnitude over, and the core SF is highly modular unlike
GemFire/Geode that enables certain parts of the Framework to leverage Java
8 features that are not necessarily required by applications.
Food for thought.

+1 for JDK 8 / Language Level 8 as well.
Please remember that JDK 7 is already no longer updated - https://www.java.com/en/download/faq/java_7.xml <https://www.java.com/en/download/faq/java_7.xml> since April/2015.

True enough! I guess there's nothing preventing us from moving Geode to JDK
1.8 now.

Why do you need to wait until "customers move to 1.8" when geode is an open source product? Surely customers are using a paid support version. Am I missing something?

Re: What is Geode's language level

Oi João,
Our current source code level is Java 1.7. We just added 1.8 support
meaning that we build/compile the product under 1.7 JDK and then
test with both 1.7 and 1.8 JREs.
We won't be able to drop 1.7 support until all customers move to 1.8
(hopefully soon but probably not in 2015).

Thanks (obrigado ;) ) William.
If I were to contribute to the project with a PR, which level should I
respect?

Hi João (Opa, tudo bem ?)
Actually it's supposed to be Java 7 but there are areas that needs to be updated.
But you should be also fine to run and compile with Java 8.
