DataOuputStream should clarify that it might write primitive types as multiple byte groups

FULL PRODUCT VERSION :


ADDITIONAL OS VERSION INFORMATION :
All OS

A DESCRIPTION OF THE PROBLEM :
DataOutputSteam function writeInt() should create a 4 byte packet but instead creates 2 packets. 1 is a 1 byte packet and then it is followed by a 3 byte packet.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Use wireshark to monitor packets being sent by server to client through writeInt(). Compare with writeLong().

Source code attached is two separate programs, one for server and one for client.


REPRODUCIBILITY :
This bug can be reproduced always.
