>          Issue Type: Bug
>          Components: Properties
>    Affects Versions: 3.2.2
>            Reporter: Philip Hodges

> /**
>   * Save the properties to the given output stream.
>   * ...
>   * @throws IOException if an IO error occurs - no it does not.
>   */
> public synchronized void save(OutputStream output, String header) throws IOException {
> ...
> PrintWriter theWrtr = new PrintWriter(output);
>  ...
>  // theWrter.flush();
>  // missing: if (theWrtr.checkError()) throw new IOException();
> Impact: caller cannot tell if the properties were completely saved, perhaps the disk filled up instead. Missing checkError is an antipattern for PrintWriter and PrintStream.
