Not a lot, though that does involve method call overheads that you may
not want in a tight loop.
I initially created my simple ReportError logging class for Java 1.3,
before the Logger class was introduced, and, as it does what I need, have
seen no need to replace it. It was written to provide similar Java
functionality to a set of C functions that I'd been using for many years.
Its trace() methods are roughly equivalent to Logger.log(Level, String)
and Logger.log(Level, String, Object[]) with all output sent to stderr.
