Subject RE: Singleton memory leak after redeploying.

I disagree, only the most trivial webapp needs one logger. A web
application consisting of a large number of subsystems, potentially
managed/analysed by different teams should be logged to different
locations. Effective debugging will come down to a well organised
logging structure.

I think it's not a good idea to have a lot of logger objects in a webapp
In a webapp, you need only one logger.

Then, on the last servlet destroy, you can freed your logger with
logger=null; I think no other method is needed.
