Version for node and java

[glsp-bot]

I am currently preparing a docker build for both java-application and node-frontend.
I was wondering, why the Readme.md states that version 8 should be used for node? LTS is currently at 12.13.1 - is there a specific reason for this?

Also regarding the java application I have not found any documentation on a specific openjdk version (I assume we use openjdk?) Are there any preferences or should I just use openjdk 13?

I'm not sure for Node, but for JDK I would stick to 11, as it's the current LTS version

The baseline for the java applications should be (open) JDK11

For Node I don't see a reason to not update to the latest LTS

[tortmayr]

I disagree. We have to fulllfill the prerequisites for Theia. According https://github.com/eclipse-theia/theia/blob/master/doc/Developing.md#prerequisites the version should be Node.js >= 10.11.0 AND < 12.x.

It seems the incompatibility with Node 12 has been fixed now

[CamilleLetavernier]

But to be safe, staying within Theia's recommended version and LTS seems the way to go :)

Are there any benefits of using Node 12? Otherwise I would stick with Node 10 (as long as Theia is using it) to minimize potential build issues.
