Fixes #1551

Notes

As far as I can see, this is not a breaking change because the only thing from unleash-client-java exposed from the open-feature Unleash provider is the configuration builder and it does not seem to have changed since v9.
To be double checked though.

The main open questions now are:

• how to deal with the tests? apparently there is now a new schema for features.json (v2 while we test with v1) and
  • v1 is still supported but some things behave differently, see the one failing test (stickiness is not set in Variant anymore by Yggdrasil)
  • v2 would need to be tested maybe? at least a simple test
  • example of v2 config: https://github.com/Unleash/yggdrasil/blob/main/java-engine/src/test/resources/custom-strategy-tests.json
• we need to manually do a test (on all Yggdrasil supported arch) to validate that indeed, When running java application it fails loading libgcc_s.so.1 Unleash/unleash-java-sdk#275 is really fixed as it seems to be
• someone much more familiar with Unleash than me should obviously double check that I didn't forget anything that is not just type errors :)

Thanks! Looks good to me.

thx @beeme1mr, do you have an opinion about the open questions for the tests? Maybe I'm overthinking things and it's alright to just trust the unleash dependency?

good questions, I would say adjust v1 failing test to make tests pass and add v2 tests similar to v1, and enhance them.

reg. libgcc_s.so.1 used by WASM, I don't think the tests here must cover it, as testing it may require configuring and maintaining Docker containing some libraries just for tests, and here we test the provider, and not the Unleash SDK.

Thx @liran2000 :)

So actually it seems that the difference between v1 and v2 is just about the way segments are returned, and I don't think we use this at all here. Also it's kind of hard to find anything about the schema and how they differ from each other (I just found a mention of that segments thing in https://docs.getunleash.io/reference/api/unleash/get-all-client-features#responses. I concluded that it wasn't worth our energy to try to test too much things except changing the version to v2 in the json test file.

I also created Unleash/unleash-java-sdk#316 in case it's not normal that the stickyness is null when returned by the Unleash SDK and added it as a comment in the test.

reg. libgcc_s.so.1 used by WASM, I don't think the tests here must cover it, as testing it may require configuring and maintaining Docker containing some libraries just for tests, and here we test the provider, and not the Unleash SDK.

I will try to make some tests on my side then just to ensure all is good, but I will be away for 2 week before I can do that, so maybe we want to merge this before and see how it goes? Clearly the doc is very explicit about the fact it should just work.
