Bad String.format() call in Formatting

[martinrleon]

I hope you don't mind me posting issues I come across. I know you are currently working on this repository, but we are in urgent need of a version of FEST that will work with Java 1.7. The current code snapshot seems to address the problem I reported (Issue #2 ).

Hopefully there are only minor issues still remaining to address, like the following.

There are 2 '%s' format specifiers but only one argument provided.

Please let me know if you prefer I not continue posting issues I come across.
