[brevilo]

• Using OSGi's Service Loader Mediator (i.e. Apache Aries SPI Fly)
• Made all requirements optional (minimally invasive change)

@andymc12, feel free to merge my changes into a PR of your own (regarding authorship).

Hi @andymc12, do you think this one is ready to merge now...? 😏

[andymc12]

Sorry for the delay on this @brevilo - thanks again for the PR!

[brevilo]

Thanks! Anytime!

[brevilo]

BTW, how about another (RC) release? 😏 Would love to get rid of another fork...

Hm, @andymc12 can you please check that again? I don't tink it's part of that release candidate: https://github.com/eclipse/microprofile-rest-client/compare/2.0.1-RC1...2.0.1-RC2 (or any tag for that matter, just in master so far).

Thanks

@brevilo good catch - I must not have backported the changes to 2.0.X-service before publishing RC2. I have published RC3 now which show your latest change and mine: https://github.com/eclipse/microprofile-rest-client/compare/2.0.1-RC2...2.0.1-RC3

Here is the release page: https://github.com/eclipse/microprofile-rest-client/releases/tag/2.0.1-RC3

Thanks!

You're welcome 👍 Thanks for the swift action - works like a charm!
