Haven't yet done the "convert into a value" yet, but this is a reasonable start.

The tests run. Feel free to provide additional test case suggestions.

Hey @justinabrahms, thanks for putting this together. It's great to see new providers like this added to the contribs repo. I'll let @toddbaert and/or @Kavindu-Dodan handle the full review (I'm not a Java person) but the basics look good.

By the way, flagd extends JSON logic to support deterministic splits. If that's ever a requirement here, please consider using the same flag configuration and hash algorithm.

Could you add a src/ dir under the inline-evaluating-provider dir and put the source and test files there, like in the other libs? I think as it stands this might cause some issues because it's not a standard maven project dir.

EDIT: Actually, after testing a bit I don't think your tests are running in the CI for this reason, and the package will probably contain no bytecode. I added a test that should have failed and it did not.

[toddbaert]

Looks good in theory, but I think you'll need to resolve this or no actual java bytecode will be published.

You may want to add an entry here, or this will default to 1.0 on release (up to you though).

LGTM with the exception of the metadata as @thiyagu06 pointed out: #241 (comment)

Approving with some comments :)
