> Key: OAK-6707

> Labels: technical_debt
> Fix For: 1.9.0, 1.10
>
>
> Invoking TarWriter.close() on an already closed writer throws an {{ISE}}.
> According to the general contract this is not allowed:
> {code}
> * Closes this stream and releases any system resources associated
> * with it. If the stream is already closed then invoking this
> * method has no effect.
> {code}
> We should adjust the behvaviour of that method accordingly.
> Failing to comply with that general contract causes {{TarWriter}} instances
> to fail in try-resource statements when multiple wrapped streams are involved.
> Consider
> {code}
> try (
> StringWriter string = new StringWriter();
> PrintWriter writer = new PrintWriter(string);
> WriterOutputStream out = new WriterOutputStream(writer, Charsets.UTF_8))
> {
> dumpHeader(out);
> writer.println("");
> dumpHex(out);
> writer.println("");
> return string.toString();
> }
> {code}
> This code would cause exceptions to be thrown if e.g. the
> {{PrintWriter.close}} method would not be idempotent.
