Ubuntu 16.04 - which java package do I want?

[matt91]

Just setting up a new Ubuntu 16.04 build. I can't recall, which java is recommended?

(This is SageTV server-only)

thanks

matt@poweredge:~$ java -version
The program 'java' can be found in the following packages:
 * default-jre
 * gcj-5-jre-headless
 * openjdk-8-jre-headless
 * gcj-4.8-jre-headless
 * gcj-4.9-jre-headless
 * openjdk-9-jre-headless
Try: sudo apt install <selected package>

I'd google for installing Oracle JRE. You have to add a PPA.

OK, thanks.

I followed this guide (for installing on Digital Ocean)
https://www.digitalocean.com/communi...n-ubuntu-16-04

and ended up installing: oracle-java8-installer

Haven't gotten to installing Sage yet, but hopefully this is what I need.

matt@poweredge:~$ java -version
java version "1.8.0_131"
Java(TM) SE Runtime Environment (build 1.8.0_131-b11)
Java HotSpot(TM) 64-Bit Server VM (build 25.131-b11, mixed mode)

I faced the same dilemma, I don't think there is an "official" answer.

If you are running a headless server (no desktop, no X11) I think you can install openjdk-8-jre-headless, default-jre otherwise and it should work. I tried it and it does seem to work fine...BUT...

If you read the build directions on Git, about half way down the page you will see the builds are made with Oracle Java (the real deal). Knowing this I backed out of OpenJDK and installed Oracle Java 8 "just in case". There are instructions here on how to install it.

That said, I never had an issue with OpenJDK for the very short time I used it with SageTV.

It shouldn't be a problem to use OpenJDK since SageTV doesn't use any of the proprietary Oracle things. Of note is that the Docker container also uses Oracle Java.

The only reason that I know of to use Oracle vs OpenJDK is that Oracle java includes some image formats that are not in the OpenJDK. I know in using Phoenix where there are some image manipulation APIs that some of these APIs fail under OpenJDK (at least the unit tests fail). But I think for the most post, you can use either.

Interesting. I did not know that.
