> Hi Markus, did you double check with all the existing subclasses of `BufferedInputStream` that the new implementation of `transferTo` will not cause trouble, if any of the subclasses is overriding `int read(byte[] b, int off, int len)`? If I'm not mistaken - with this new implementation of `transferTo` then `BufferedInputStream::read(byte[] b, int off, int len)` (a public method that can be overridden) will no longer be called by `transferTo`. This could be causing problems if `read` is overriden to do some special processing in the subclass.

Thank you, good catch! I will check the subclasses contained in OpenJDK! 👍
