Subject: Re: [DISCUSS] Supported Java version
I didn't think that we agreed to bumping the java version to 7, and it seems
like that might make working with distros / packages difficult.
Adding Alex and Frank to the CC to get their take.

Hi,
So the last couple of days the master branch wouldn't build on my systems:

So I'm running Ubuntu 12.04.1 on all my systems (laptop, desktop,
servers) and this is the maven information:
wido@wido-desktop:~$ mvn -v
Apache Maven 3.0.4
Maven home: /usr/share/maven
Java version: 1.6.0_27, vendor: Sun Microsystems Inc.
Java home: /usr/lib/jvm/java-6-openjdk-amd64/jre
Default locale: en_US, platform encoding: UTF-8 OS name: "linux",
version: "3.2.0-38-generic", arch: "amd64", family: "unix"
wido@wido-desktop:~$
Now, that Java version is old, I know, but it's the openjdk version
which is in Ubuntu 12.04's repositories right now.
I downloaded Java 7:
wido@wido-
desktop:~/repos/cloudstack$ JAVA_HOME="/opt/jdk1.7.0_15" mvn
-v Apache Maven 3.0.4 Maven home: /usr/share/maven Java version:
1.7.0_15, vendor: Oracle Corporation Java home: /opt/jdk1.7.0_15/jre
Default locale: en_US, platform encoding: UTF-8 OS name: "linux",
version: "3.2.0-38-generic", arch: "amd64", family: "unix"
wido@wido-desktop:~/repos/cloudstack$
With that Java version the master branch builds just fine.
What I want to discuss which version of Java we support.
I'd say we support the LTS version of any major release of CentOS or
Ubuntu.
I also understand that Java 6 is pretty old, so what do we do?
