--------------------------------------------------------------
Based on the stack trace, It looks like we forgot to duplicate the field
serializers when duplicating {{BaseRowSerializer}}. And it works fine after I
duplicate the field serializers like this
{code:java}
TypeSerializer<?>[] duplicateFieldSerializers = new
TypeSerializer[fieldSerializers.length];
for (int i = 0; i < fieldSerializers.length; i++) {
duplicateFieldSerializers[i] = fieldSerializers[i].duplicate();
}
return new BaseRowSerializer(types, duplicateFieldSerializers);
{code}
