the value don't equal xxhsum,the value length is 15

I know

this is java long type precision lost,
The following two methods are ok.

import com.sun.org.apache.xerces.internal.impl.dv.util.HexBin;
...
        long value = streamingXXHash64.getValue();
        BigInteger bigInteger = BigInteger.valueOf(value);
        return HexBin.encode(bigInteger.toByteArray()).toLowerCase();

    public static String printHexString(byte[] b) {
        String res = "";
        for (int i = 0; i < b.length; i++) {
            String hex = Integer.toHexString(b[i] & 0xFF);
            if (hex.length() == 1) {
                hex = '0' + hex;
            }
            res += hex;
        }
        return res;
    }

long l = 497568829116747426L;

this long value to hex should be 06e7b836becf8ea2

but Long.toHexString(value).toLowerCase(); is 6e7b836becf8ea2
