Add public EMPTY constant in StringUtils [SPR-17590]

[spring-issuemaster]

Ankur Pathak opened SPR-17590 and commented

All spring projects are using "" as empty string. And "" is scattered at all places in all Spring projects. It would be better to add public constant

EMPTY in StringUtils and use it in all spring projects. 

I will be providing a pull request for this issue.

It would be better to add public constant

While that may be true for String constants in general—to reduce typos, I don't think this holds true for empty strings. I would argue that "" is more readable than EMPTY, and it is 60% shorter to type as well.
