According to JVMS 4.7.9.1 https://docs.oracle.com/javase/specs/jvms/se24/html/jvms-4.html#jvms-4.7.9.1 `ThrowsSignature` is only valid in `MethodSignature`s. Previously, we add `^...` ThrowsSignature no matter the symbol is method or not. We just ignore @throws annotation on invalid locations.

There was a problem hiding this comment.
Good fix to have for 3.9, but should we error about this earlier in the pipeline? Presumably a developer would do this because they intended to put it somewhere else.

Yeah, and in fact, Scala 2 already emits error earlier in the pipeline. I'll open an issue 👍 |
