I believe you have to resize the buffer and try again. i.e.

private int appBBSize;
private int netBBSize;
private ByteBuffer inNetBB;
private ByteBuffer outNetBB;      

case BUFFER_UNDERFLOW:
netBBSize = sslEngine.getSession().getPacketBufferSize();
    if (netBBSize > inNetBB.capacity()) {
        ByteBuffer bb = ByteBuffer.allocate(netBBSize); //Resize
        inNetBB.flip();
        bb.put(inNetBB);
        inNetBB = bb;
        break; //Try again
    }
