The tool seems to scan folders as well as Java files, and comes up with errors such as:

[INFO] files to be scanned: /Users/martijnverburg/workspace/microsoft/gctoolkit [ERROR] Not a regular file: /Users/martijnverburg/workspace/microsoft/gctoolkit [ERROR] Not a regular file: /Users/martijnverburg/workspace/microsoft/gctoolkit/vertx [ERROR] Not a regular file: /Users/martijnverburg/workspace/microsoft/gctoolkit/vertx/target [ERROR] Not a regular file: /Users/martijnverburg/workspace/microsoft/gctoolkit/vertx/target/test-classes
