bug in decode payload length

[dawud-tan]

Hello Mr. Blink, your code line 430 as shown in this link
https://github.com/blinkdog/websocket/blob/master/src/main/java/com/pmeade/websocket/io/WebSocketServerInputStream.java#L430

for (int i = 0; i < NUM_OCTET_64; i++) {
                payloadLength |=
                    inputStream.read() << (NUM_OCTET_64 - 1 - i) * OCTET;
            }

the result of inputStream.read() should be casted to long first, since bitwise OR between Long number and Integer number will result in Integer number.
you may check this code snippet

long payloadLength = 0L;
int[] testData = new int[]{1,1,1,1,1,1,1,1};
for(int i=0; i<8; i++){
    long byteN = testData[i];
    payloadLength = payloadLength | byteN << (7 - i) * 8;
    System.out.print("i[" + i + "] payloadLength: ");
    printBinaryform(payloadLength);
    System.out.print("\r\n="+payloadLength);
    System.out.println();
}

following is the output of code above:

long payloadLength = 0L;
int[] testData = new int[]{1,1,1,1,1,1,1,1};
for(int i=0; i<8; i++){
    payloadLength = payloadLength | testData[i] << (7 - i) * 8;
    System.out.print("i[" + i + "] payloadLength: ");
    printBinaryform(payloadLength);
    System.out.print("\r\n="+payloadLength);
    System.out.println();
}

The output of code above:
