Another more targeted interface is `CompilationFailedIndicator`.
This interface is used to indicate that the exception is caused by a compilation failure.

            We check the binary compatibility by comparing the current code’s binary interfaces
            against THE LATEST VERSION WHICH IS RELEASED FROM RELEASE BRANCH (from `released-version.json` on this branch)
            AND LOWER THAN CURRENT BASE VERSION (from `version.txt` on this branch).
