Convert the string that has been accumulated into an Object. Subclasses
may override this. Note that if the javaType is a primitive, the returned
object is a wrapper class.
Object result;
if (javaType == byte[].class) {
result = HexBinary.decode(source);
} else {
result = new HexBinary(source);
}
if (result == null) result = new HexBinary("");
return result;
