protobuf 4 incompatiblity?

Hi @loosebazooka ! Thanks for the issue; I'm sorry for my late reply, and that you're having issue building the fuzzer for fuzzing protobuz for sigstore-java. A quick search shows you're using JUnit 5, so that is good.
I'm not super proficient on oss-fuzz. But you can try again with Jazzer?

Sorry I know that was a lot of info, I'm working on a reproducer right now, trying to get something minimal. These tests don't use junit5. They follow the process outlined in the ozzfuzz docs for jazzer (https://google.github.io/oss-fuzz/getting-started/new-project-guide/jvm-lang/)

So maybe I don't understand what's going on with the oss_fuzz build, but it appears to be a 2-step process where there's a build phase and a run phase.

The build phase in this case appears to be executing fuzzers though? Anyway, this appears to be a genuine issue discovered by fuzzing just at weird "build" phase of the fuzzing process (on oss_fuzz). Any idea who would be the right person to direct this to?

Yeah, that's a tough one. I'm really not the expert on oss-fuzz and jazzer for this situation. It seems like this is urgent or a task that you need to finish quickly. Is that an accurate assumption? In which case, can you email me at [email protected] ?

It's not super urgent. But I can still email you if it makes sense

Yeah let's move it to email so I can get the whole picture.

Thank you!
