seeking guidance - wrapping Log4j

[Lutz Michael <mi...@siemens.com>]

I receive regular questions from internal customers asking why it is
recommended to wrap Log4j through aggregation as opposed to inheritance.

I am familiar with the ClassCastException issue found in
http://jakarta.apache.org/log4j/docs/TROUBLESHOOT.html#cce.
I have purchased the Log4j Full Manual, and will search for information in
this regard.  I've noted there is a section in the book covering wrapping
Log4j.

In addition, would someone please comment on the technical reasons
aggregation is recommended, as opposed to sub-classing?

Thanks for your time.

Mike
