The following line is wrong:
while ((len = bis.read(buf)) > 0) { //Same result using only 'is'
read == -1 marks the end of the stream. 0 shows only that the stream is
still waiting for the next chunk of data.
Please read the JavaDocs:
> Returns:
> the number of bytes read, or -1 if the end of the stream has been reached.
while ((len = bis.read(buf)) >= 0) { //Same result using only 'is'
if (len >0)
out.write(buf, 0, len);
else
// prevent high CPU load
LockSupport.parkNanos(TimeUnit.MILLISECONDS.toNanos(500));
}
