Unfortunately, as we have experienced so far, this isn't possible with GHA because the exact package versions aren't kept available for very long. I suppose it would be possible with very diligent watching for new versions and manually testing and updating before the old version disappears, but that doesn't seem feasible in practice. On the other hand, I don't think we have actually seen any problems when bumping the versions so far, so I'm now inclined to agree with this change.

Maybe we could use [devkits](https://github.com/openjdk/jdk/blob/master/doc/building.md#cross-compiling-the-easy-way-with-openjdk-devkits) to pin the compiler version? I'm not sure how feasible that is in the GHA context. It might have a negative performance impact?
