If I don't synchronize this method I'll get wrong values?

Question

public static int getCRC16(byte[] bytes) {
    CRC16 crc = new CRC16();
    crc.reset();
    crc.update(bytes, 0, bytes.length);
    return (int) crc.getValue();
}

Tons of threads will hit this method, if I don't synchronize I'll get a wrong crc for a specific thread?

No, it is fine, as long as you don't use any shared variables. The bytesand crcare local per thread. That's why they are called local variables.
