John mentioned that he had several logging systems to contend
with. Moreover, log4j and logback can print the invoking thread's name
whereas j.u.l. will print the thread's id (an integer).

While in the general case on cannot be certain that thread name will
be printed, in the common case where log4j is in use, there is imho no
point in adding Thread.currentThread().getName() to the log message. I
guess that it really depends on the particular case being addressed.
