Description

The following 2 key values if encoded and decoded, produce wrong results:

byte[] row = Bytes.toBytes("abcd");
byte[] family = new byte[]

{ 'f' }

;
byte[] qualifier0 = new byte[]

{ 'b' }

;
byte[] qualifier1 = new byte[]

{ 'c' }

;
byte[] value0 = new byte[]

{ 0x01 }

;
byte[] value1 = new byte[]

{ 0x00 }

;
kvList.add(new KeyValue(row, family, qualifier0, 0, Type.Put, value0));
kvList.add(new KeyValue(row, family, qualifier1, 0, Type.Put, value1));
