Remarks
Copies all bytes from a file to an output stream.
If an I/O error occurs reading from the file or writing to the output stream, then it may do so after some bytes have been read or written. Consequently the output stream may be in an inconsistent state. It is strongly recommended that the output stream be promptly closed if an I/O error occurs.
This method may block indefinitely writing to the output stream (or reading from the file). The behavior for the case that the output stream is asynchronously closed or the thread interrupted during the copy is highly output stream and file system provider specific and therefore not specified.
Note that if the given output stream is java.io.Flushable then its java.io.Flushable#flush flush method may need to invoked after this method completes so as to flush any buffered output.
