Exceptions should only be logged if unhandled

[brycelelbach]

[reported by blelbach] [Trac time Tue Jan 10 19:19:10 2012] I get this exception, logged to a file, when I use any application other than the sine application with the sine component built. The exception is not propagated to the program.

[comment by hkaiser] [Trac time Tue Jan 10 19:48:30 2012] That's what's expected.

[comment by blelbach] [Trac time Tue Jan 10 19:56:07 2012] Huh?

How is an exception expected behavior? Are you telling me that the generation of a log file and error is intentional?

[comment by blelbach] [Trac time Tue Jan 10 20:01:41 2012] I think it is poor design to force all applications to generate a logfile every run with the default logging parameters just because the sine performance counter wasn't loaded. Even component module loading warnings don't cause this. Can you please fix this to not generate a log message at the level?
