I had actually posted that before understanding all of the code. It was
done that way by
design to avoid having the full stack dumps printed out. In most cases,
the final exception
should be giving you the necessary information to fix the problem. Where
it does not,
that should be changed.
The ExceptionUtil class is useful as a public class because it lets
other classes handle the
CascadingThrowables however they like. The Avalon Log Formatter for
example will print
out the full stack trace along with the stack traces of the exception
which caused it.
Cheers,
