1Without seeing actual use case it is difficult to answer. I prefer using emptyObject/NullObject instead of null. So StringUtils.EMPTY is good choice. – Jayan Sep 18 '13 at 04:12

Do not use null.
Since it's a message you might showing it some where,If you set it to null,it displays as "null" to end user.
Try like ,
private static final String EMPTY_STRING = "";
setMessage(EMPTY_STRING );
on there other hand you can check with isEmpty method,instead of checking null.

*"Do not use null"* - I would argue that is contextual. A `null` value may have special meaning to the object it's being set to - IMHO – MadProgrammer Sep 18 '13 at 04:18
