feat(setup): Allow CE users to select their java version

[mzico]

It would be nice if we could allow CE users to select their java version during installation just like janssen ( -java-version {11,17}]
)

@yurem does all CE components run on java-11 without issues?

[moabu]

I don’t think allowing users to select java versions is necessary. It will create a support burden we don’t need. We are better off supporting a specific java option . In this case 17.

[yurem]

@devrimyatar I tried to upgrade jdk in already installed 4.5.5 environment. All services worked well.
I agree, one option is better. If QA will confirm that there is no issues with jdk 17 we can use it in new release.

[mzico]

OK, if providing option create too much issues on supporting product then let's not do it. We are going with Java 17 in 4.5.7 ( whose release date is Feb, 2025 )

Quick question @yurem @devrimyatar @moabu : if we can support Java 17, why not the latest stable one... which is 23?

[moabu]

If we can handle it without regression I think it would be fine. The main issue is with what needs to be changed in terms of code to allow for us to run with 23. Its a trade off that would make more sense for jans vs gluu4.

@yurem : any help on last question?

[yurem]

@mzico I agree with @moabu about using version 17
23 version requires code changes. And latest one no mean stable one.
