Switches sample to Java 17 as default.

Additional space added to the Java backend to accommodate downloaded JRE. Sidecar is also grew bigger.

Hello @vmikhailenko
Could you please explain why this upgrade to java 17 was done?

[beckermarc]

As of CAP Java 1.31.0, which was released end of January Java 17 is the recommended Java version. This is documented in our release notes: https://pages.github.tools.sap/cap/docs/releases/jan23#jdk-17-support. To reflect this also in our sample application, we made this change.

@beckermarc thank you for this feedback.

Does the SBAS environment need to upgrade?

Does the SBAS environment need to upgrade?

Yes I think Java 17 should be available in BAS and easily usable. It might also make sense to make it the default.

@beckermarc
currently we use this SBAS env : https://sap-ux-stage.cry10cf.int.applicationstudio.cloud.sap/index.html
& it has 11, therefore now when we use this repo in SBAS, we get the error reported in the community.

Do you know when the SBAS will be upgraded to 17?
did SBAS confirm they will install version 17?

[beckermarc]

As said in our internal chat, I'd recommend to get in touch with BAS colleagues. For the time being you can also simply change the jdk.version property in pom.xml to 11 in your local clone. Then the project will run with Java 11. So far no Java 17 specific features are used.
