> XMLLoaderBufferedPositionedInputStream caches passed InputStream and then uses it to read. At the same time the stream is bufferent in super construcor. So cached version is unbuffered.
> Also using cached version makes getPosition() call return invalid values and forces XMLLoaderBufferedPositionedInputStream maintain it's own counter.
