Prohibited exception thrown

Reports throw statements that throw an inappropriate exception. For example an exception can be inappropriate because it is overly generic, such as java.lang.Exception or java.io.IOException.

Example:

  void setup(Mode mode) {
      if (mode == null)
          throw new RuntimeException("Problem during setup"); // warning: Prohibited exception 'RuntimeException' thrown
      ...
  }
