Hi all,

I noticed some lines (about 1350) like this

logger.fine("some message: " + varForDetail);

in our code.

This is 'equal to'

logger.log(Level.FINE, "some message: {0}", varForDetail);

but it seems like this second form is about 7 times faster to execute,
if the logging level is Level.INFO....
