Reading Data From Socket / Responses Of Python Server

I'm having a lot of problems reading data from a socket. I'm trying to read the responses of a python server. I've a

BufferedReader inputStream = new BufferedReader( new InputStreamReader(socket.getInputStream()));

And then:

char[] messageChunk=new char[32768]; //32768
List<Byte> messageBytesList = new ArrayList<Byte>();
while (inputStream.ready()) {
inputStream.read(messageChunk, 0, 32768);
for(int k=0;k<32768;k++){
messageBytesList.add((byte)messageChunk[k]);
}
}

inside a thread. Then I convert the list of bytes to a byte array using:

Byte[] messageBytes = messageBytesList.toArray(new Byte[messageBytesList.size()]);
byte[] message = ArrayUtils.toPrimitive(messageBytes);

The problem is that I often receive ArrayOutOfBound errors when I try to parse the byte array. I think that I'm reading from the socket in a wrong way..
