This is probably just a temporary error in thinking, but IOExcpetion 
doesn't define any additional methods or properties beyond what 
Exception defines (I'm ignoring "parameters").  So no worries there.

As for what you are logging, it's "ex."

Probably Exception.  At least must be Throwable.  No I don't have a 
revised JLS handy, I'll take a look.
