fooInstance.setLogger(getLogger());

fooInstance.setLoggerFactory.getLogger());

This "migrator" doesn't seem to have any intelligence at all. It even leaves me

It's going to be easier to convert all these source files by hand. This
migrator doesn't seem to be worth much---it seems to me that a couple of
regular expressions, while far from perfect, would do a better job than this
migrator.
