This is what I was talking about being “frowned upon”. Even if you specify -source and -target, you can accidentally compile in e.g. calls to methods that don’t exist in older JDK standard libraries, so the program will fail at runtime on old JDKs. In practice it’s not that common a problem. -Aaron
