There is 1 already:

http://hg.openjdk.java.net/jdk/jdk/file/2dedeaa537a2/test/micro/org/openjdk/bench/java/util/logging/LogRecord.java

I've moved my two logging benchmarks to that directory, too; I think it 
makes sense.

Also, per the discussion with Claes, I've reduced the number of values 
in the 'depth' @Param.
