public class LoggerRuntime extends AbstractRuntime
IRuntime
implementation uses the Java logging API to report
coverage data.
The implementation uses a dedicated log channel. Instrumented classes call
Logger.log(Level, String, Object[])
with the class identifier in the
first slot of the parameter array. The runtime implements a Handler
for this channel that puts the probe data structure into the first slot of
the parameter array.
