Actually this is a good solution. To pre-allocate exceptions
with a small stack trace! Thank you for the good idea.

The solution could be even spun further. Why not create
a separate thread, that will provide a service that
will create exceptions without a big stack trace. Will
need a little synchronize, but could also work.

Well it exists in JDK 1.7 for some reason. But you cannot
do it off hand, you can only do it for your own exceptions
since the constructor is protected.

I guess a typical usage scenario would be the creation
of a stack overflow exception or a memory exception, so
as to allow the application to recover.

Usually a stack overflow exception is not so interesting,
most often it is caused by a loop that starts somewhere
and all you have is the same method displayed over an over.

gr8, one more business case!
