It's a JMSQueue-based appender. It was written for log4j (only recently
have we switched to logback) which didn't have one. In addition to the
JMS functionality, at the other end of the JMS socket sits a server
application written in C with its own legacy logging system that must be
catered to. This involves some special formatting and data which is
neither necessary nor desirable for inclusion in the local logging that
the client-side application also needs. The appender is perhaps the
most convenient place to do this.
However, I do suppose that I should look at the layout and custom format
specifier supported by logback as a possibly better way to accomplish
the same thing. But what I have seems to work.

I'm curious: what use-case is fulfilled by the additional messages

We have a custom appender that may itself need to issue logging

System.out.println for lack of a better solution.
I suppose there must be a better way.
What would that be?

A technique that seems to work is to NOT declare a logger in the
Appender class that you want to use one from, but instead create a static
logger instance somewhere that is accessible through static methods. That
way the logger does not need to be created at the time of appender
instantiation.
