Using JDK 8 features in naryana

mmusgrov Jun 5, 2015 10:29 AM

We now compile on JDK 8 to accommodate some of our users and to take advantage of bug fixes etc. I am interested in getting feedback on what, if any, negative impact there would be on our users if we also started using JDK 8 features. For example, do all of our target platforms (Android for example) support JDK 8.

It looks like JDK7 is what is supported on Android: https://developer.android.com/sdk/index.html

Personally I think we should keep compatibility levels the same for existing features but should consider JDK8 language facilities for new features. This will help if we need to backport bug fixes.

Lets go with:

New features - can use JDK8
Bug fixes to existing supported features - use JDK7

We have an issue (JBTM-2432) that means we can only test against the IBM J9 JVM on Java7 only so if we start using Java 8 features then we will no longer be able to run the IMB jdk CI job.

Isn't there a J9 that runs on Java8?

I think there is. Mike, I updated JBTM-2432 with how to access it on Chrome
