> A large number of metrics APIs seem to declare to throw IOExceptions 
> needlessly. (incrementCounter, decrementCounter etc.)
> This is not only misleading but it fills up the code with unnecessary catch 
> blocks never to be reached.
> We should investigate if these exceptions are thrown at all, and remove them 
> if  it is truly unused.
