This is not a common situation, but it can come up in some contexts related to automated tooling (e.g. an automated tool runs compilation with -XepPatchChecks against a repo in which Gradle build configuration disables the check).
To reproduce, run ./gradlew compileJava in this repo. The Error Prone version can be adjusted in the lib/build.gradle file.
In 2.18.0, there is no stacktrace and the patch is created. In 2.19.0 and 2.19.1 (the latest at time of writing), the stacktrace occurs and the compilation fails.
