Find a community/project that interests you, I've gone with feign. Head on into the issues tab, and you'll see all the potential contributions you could make. Starting out, it's a good idea to search for tags like "bug", or "good first issue".

3 projects | /r/java | 2 May 2021

At the risk of doxxing myself, I'm a contributer attempting to fix this issue with this pr. The project has existed for a while now, and since I'm not part of the openfeign team, so the final solution they end up using isn't up to me. So there's technical debt to deal with (how the project is built and tested currently) and whether or not multi-release jars are the best solution in this case.
