Help with JIT talk for tomorrow

[Charles Oliver Nutter]

Hey all...I'm updating and expanding my talk on C2 and will be posting
some questions. Hopefully there's someone out there who can answer
them :)

First up... given this output from PrintCompilation, what do the "!"
and "n" and "%" mean?

Also, in Java 7 there's now two numbers instead of one at the begining
of the line...what are they?
