'throw' inside 'finally' block

Reports throw statements inside finally blocks. While occasionally intended, such throw statements can hide exceptions thrown from the try and catch blocks, thereby complicating the debugging process.

Example:

  class Fascinating {
    void doTask(Task t) {
      try {
        t.activity();
      } finally {
        if (!t.finish()) {
          throw new IllegalStateException();
        }
      }
    }
  }
