COERInteger encode negative number error

[Eivense]

Hi,pvendil @pvendil

l found when the value is negative (e.g. -10000),it will be encode to 0000D8F0.
When decoding, it is calculated as 55536,-10000 need to be encoded to FFFFD8F0
When the value is negative,the buffer need to be filled with 0xff

private void serializeSigned(DataOutputStream out) throws IOException {
		byte[] val = value.toByteArray();

		int signOctet = 0;
		if(val[0] == 0x00 && val.length > 1){
			signOctet++;
		}
		
		if(isSignedAndBetween(NEGATIVE_TWO_PWR_63, TWO_PWR_63_MINUS_1)){
			byte[] buffer = new byte[getSignedBufferSize()];
                        // if value is negative buffer need to be filled with 0xff
			System.arraycopy(val, signOctet, buffer, buffer.length - (val.length -signOctet), val.length -signOctet);
			out.write(buffer);
		}else{
			COEREncodeHelper.writeLengthDeterminant(val.length-signOctet, out);
			out.write(val, signOctet, val.length -signOctet);
		}
	}

Hi,

It seems you are right, I will look into this, hopefully in the coming week with a fix for this.

Hi sorry for late reply, I have now update the code to encode COER integers properly. And it included in release 2.0.0-Beta4
