apprently, this clearAnnotations clear everything https://github.com/eisop/checker-framework/blob/481040f5af69012d3b410e1844f31d84fff7b7c4/framework/src/main/java/org/checkerframework/framework/stub/AnnotationFileParser.java#L1524.

A side comment: you are using ./checker/bin/javac which automatically adds all CF jar files. You only need to add the directories with the test annotations, if they are necessary.

Thanks, I have updated the description.
