Maybe the tension is a manifestation of the problem of trying to assign 
one common severity to entering and exiting messages.  Some entries 
have to be more significant than others, the only mechanism to 
distinguish them in the JSR-47 is to not instrument the less 
significant entry points.

Maybe adding a

entering(Level level, String...)

The JSR-47 adapter could map this the JSR's entering if level was the 
equivalent of FINER or lower and fabricate a similar message if the 
level were higher than finer.
