James Carman commented on LANG-452:
-----------------------------------
This wouldn't be a new String instance. This is the empty string literal. All
literals will refer to the same object. Try it out:
{code}
System.out.println("" == StringUtils.EMPTY);
{code}
> ObjectUtils.toString() should return constant empty String from
> StringUtils:EMPTY instead a new Empty String
