The method PropertyListParser.parse(InputStream) is documented as

Parses a property list from an InputStream. This method does not close the specified input stream.

Unfortunately the underlying Xerxes XML parser does close the InputStream.

As a workaround I wrap the InputStream to ignore close():

      PropertyListParser.parse(
          new FilterInputStream(inputStream) {
            @Override public void close() {}
          });

I see two ways to fix this bug:

1. Update the documentation to point out that the InputStream might be closed.
2. Update the implementation to wrap the InputStream to ignore close().
