Boo! ;)
Seriously for a moment. I think the usage of commons-lang is beginning to
hit the up-curve. It's creeping into projects and people are starting to
talk about it [along with other Commons things] outside of the usual
circles. A 2.0 soon will really take off I believe.

Re-reading Stephen's suggestion, only thing I can see is that he
suggests that isBlank("\t\n") would not be true. However a quick test
shows that trim() removes all whitespace, so I'm a believer in Gary's
point.
