There was a problem hiding this comment.
NIT: I think we could even do
final Integer refCount = snapshottedCommits.compute(releaseCommit, (key, count) -> {
if (count == 1) {
return null;
}
return count - 1;
})and adjust the logic below to a null check instead of == 0 and drop the conditional remove from the map. merge seems kind of (slightly) wrong here when we assume that we have an entry in the map for sure?
