Java 8
Still Java 8 just came out I decided to try and compile Cayenne using it
(oracle version). The code compiled without a problem. There were a bunch
of javadoc issues that caused that part to fail so I fixed all those except
this one (since I'm not sure what to change it to):
[ERROR]

This package (and the classes) DOES exist in rt.jar, so for some reason it
is just not finding it. If I comment out the apple code then the entire
build completes successfully.

Unless there is a compelling reason, I would not stop supporting Java
6 on 3.2. Most of the app servers out there still require Java 6
when I looked last month --
http://en.wikipedia.org/wiki/Comparison_of_application_servers
My primary client is once again considering switching from JPA to
Cayenne, and all of our Oracle app servers run Java 6. More on this
possibility on a separate thread.

On FreeBSD (which I track myself for work and on which many of the Jenkins slaves run) Java 8 is still in testing. I'd give it another month or so. But some of the Linux environments should have it if we bind our test runs to those slaves only.
In my own work, based on Cayenne 3.2, I'm not seeing any OSX/Java 8 issues. But I'm not running the Cayenne test suite, just our own.

Anyone knows if we have Java 8 on the CI server? Maybe we should add it to the 3.2 tests.. Another set of red balls to pay attention to :)

BTW, with DI we have a much easier mechanism to develop and maintain JDK-specific extensions. Previously we’d try to use some classpath magic to enable/disable JDK-specific features.
Now we'd just create a separate Maven module with a Cayenne DI Module class in it that bootstraps Java 8 stuff. Then a user would pass this module when creating his ServerRuntime. Very clean and deterministic.

I think it will speed up the process (even considering what I said above). I guess we’ll just sit on it for another 6-12 months, and by then many more people abandon Java 6. So dropping it won’t be as painful for the users as it is now.

We're still running Java 6 mostly because there just wasn't a compelling
reason to move to Java 7. So I'd be reluctant to drop support too quickly.
But Java 8 looks very nice; if dropping support for Java 6 speeds up the
process of getting to Java 8 then it might be worth it.
Java 8 also includes the new Date & Time API (JSR-310), which should
probably be supported in Cayenne eventually. It's very similar to Joda
from what I hear.

Yeah, this worked with Oracle Java 7, so there’s gotta be a way to make it work.
I wonder if we use this occasion to stop supporting Java 6 on 3.2. This is such an old news. Anyways just throwing it here to see if anyone has strong objections.
