Thiago Veronezi commented on JOHNZON-18:
----------------------------------------

This is an extract of the java.io.BufferedReader class...

{code}
do {
  n = in.read(cb, dst, cb.length - dst);
} while (n == 0);
{code}

If Sun/Oracle does it, we can do it too. :)

> This is related to the issue discussed 
> [here|https://issues.apache.org/jira/browse/JOHNZON-17]. Basically, the 
> "read" method might not read all the bytes at once. We need to make sure to 
> read at least one until we reach the value "-1".
