How to suppress console output when PK not found?

[markus . karg]

Is it possible to suppress the console output on the server when findByPrimaryKey does 
not find a row? The problem is, when
the user types in some search critera (a pk to lookup) it could happen as a quite 
normal reaction that the system cannot find
that pk. And we do not want our system to dump out such a lot of lines each time our 
software does a quite normal reaction...
