Set the default L & F. While I enjoy the bounty of the sixteen possible
exception types that this UIManager method might throw, I feel that in
just this one particular case, I'm being spoiled by those engineers
at Sun, those Masters of the Abstractionverse. It leaves me feeling sad
and overweight. So instead, I'll pretend that I'm not offered eleven dozen
ways to report to the user exactly what went wrong, and I'll bundle them
all into a single catch-all "Exception". Because in the end, all I really
care about is whether things worked or not. And even then, I don't care.
