We're talking about copying with provided buffer, right?
long copy(InputStream source, OutputStream target, byte buffer)
It would be very helpful to verify that this method is needed extremely rare,
if at all. In our case it would be an array of very specific
(other than 1024, 2048, 4096 or 8192) size, i.e. unusually large or small or
heavily reused one.
To copy from an input stream to an output stream you need to try to read a byte
from the input stream, at least once. Therefore search for usages of
these methods will be a good start:
java.io.InputStream#read(byte, int, int)
