>I believe we will never throw this exception outside of readResponse
No. In `postJson`, it will throw a `ConnectException` when try to get
output stream of a connection while the remote server is down. I take care of
it here:
>try {
val out = new DataOutputStream(conn.getOutputStream)
Utils.tryWithSafeFinally {
out.write(json.getBytes(Charsets.UTF_8))
} {
out.close()
}
} catch {
case e: ConnectException =>
throw new SubmitRestConnectionException("Connect Exception when
connect to server", e)
}
