> When reading a huge resource (i.e. 700MB file) the ResourceReader produces an overflow due to the BufferedOutputStream which is used (and forced to be used via AbstractReader). The BufferedOutputStream flushes only at the end (or when forced to), but overwrites the flush method to do nothing.
> As I don't know exactly where the BufferedOutputStream is used and what kind of impacts it will have to change it there I'm just going to fix the ResourceReader.
