requiring java 1.7

[Dmitriy Setrakyan <ds...@apache.org>]

Guys,

I thought we added a requirement to make sure that maven build requires JDK
1.7. But if I build with JDK 1.8 I get only compilation errors without any
explanation why.

Can someone comment on that, please?

I think it is ok to just document JDK7 requirements for 1.0 and fix it in the
consequent release. Doesn't seem like a big deal to me ;)

Re: requiring java 1.7

[Alexey Kuznetsov <ak...@gridgain.com>]

Build procedure was significantly modified in sprint-3.
If we want to try to compile sprint-2 with JDK 8 we will need to modify
pom.xml
As of we released, we cannot change anything without restart release voting.
Should I try to compile sprint-2 with JDK 8?

Dmitry, I've just tried to compile ignite-sprint-3 with Idea and comandline
maven under JDK 8.40 - all compiled without errors.

Alexey K,

The code does not compile under Java 8. I think we should either fix it to
compile or add Java 7 restriction.

Re: requiring java 1.7

I thought that we enforce JDK 7 because of our java8 backported classes.
But now we reworked code to solve this issue.
May be we do not need any more such restriction?

Curious. The forward transition should be straigh-forward, but I guess it is
possible to create some forward-incompatible code. If that's the case then an
enforcer check for 1.7 would be a good idea.

Ideally, yes. But from what I heard, it requires additional work.

Re: requiring java 1.7

Shouldn't we be able to compile with Java8 as well?
