Ehm, yes, I am actually guilty in this respect: I did this version 
upgrade, mainly to solve some dependency issues related to SLF4J, 
Commons Logging and Log4j.

This is coherent with what I've found while building C3 on different 
machines: from a fresh checkout no errors, from a source tree already 
built before updating, first an error, then everything works.

AFAIK, there should be no issue in making profiling results volatile, 
but I am really not familiar with profiling internals: who knows better?
