With log4j, the same-named logger (i.e., via the class or class name you pass to the constructor) is the same logger instance.  It is better to name a logger by the class that uses it, as documented in the log4j instructions.  This helps ops to maintain the program.  I don't know whose convenience you're trying to serve, "a", but I will bet dollars to doughnuts it's not the folks whose convenience you ought to serve, namely the production personnel.

Logging isn't for programmers, it's for ops.

I wonder if "a" means that you cannot instantiate a logger as a static variable, which of course is nonsense.  You most definitely can, and sometimes should, instantiate a logger as a static variable.

If "a" refers to objects in general, then it's even more nonsensical.  It's Java.  Of course you can instantiate objects as static members.

Perhaps "a" ought to clarify his meaning.  "a"?

Also, "a", I heartily recommend you read *and study* the documentation for log4j (or any other framework that you use).
