There is another possibility. In the current trunk version (and prior release
versions) each wrapper in JCL has a different behaviour:
Some do
String.valueOf(message);
some do
if (message == null) {
return;
}

This has to be specified in the o.a.c.l.Log interface.
I suggest String.valueOf, because an underlying log system may
detected location information and you can check the code why null
is passed.

for details.
