Subject ThreadContext - auto-closable?
Date Fri, 01 Apr 2016 10:16:21 GMT
I was looking at the ThreadContext section of the API @
http://logging.apache.org/log4j/2.x/manual/thread-context.html -
particularly the Thread Context Map

Given it's important to remember to clear the map at the "end" of
processing, would this be a good case for an auto-closeable, so you
could do something like (based on the documented example) ...

try (final CloseableThreadContext ctc = new
CloseableThreadContext("id", UUID.randomUUID().toString(),
"ipAddress", request.getRemoteAddr())) {

    logger.debug("Message 1");
    logger.debug("Message 2");

i.e. creating the object adds the key/value pairs to the Thread
Context Map, and when the object is auto-closed they are automatically
removed from the Thread Context Map (or returned to their original

Have I missed anything?

(and as I finished writing this, it strikes me that I don't need any
changes to the API, I can do this independently, but it may be worth
