Our study also reveals the disconnection between patch writers and reviewers in terms of their criteria of patch quality.
For instance, reviewers considered a patch having inconsistent or misleading documentation to be highly unacceptable. However, patch writers assigned significantly lower decisive scores to this particular reason. Interestingly, for all the patch rejection reasons that received significantly different decisive scores from patch reviewers and writers, reviewers consistently assigned higher scores than patch writers. This result suggests that patch reviewers consider certain issues of a patch more destructive than patch writers expect.
