Ahh yes, I agree, in general it is much better to fail quick,
loud and verbosely, right!

However, if this is a static { } block, AFAIK it is not defined
when it will be executed (Before application start? Or later,
when loading the class later? Or when using it first time?).

If the exception would be thrown before main() is called, I think
it is difficult to catch it. I think some general global hook
must be used to do so.

Simpler to handle, if it is thrown when invocating some function,
then it can be caught by try { } catch.
(or am I wrong or outdated?)

oki,

Steffen
