Subject [jira] [Created] (LOG4J2-1296) Add MessageFactory that reuses a cached Message instance
Date Tue, 23 Feb 2016 13:53:18 GMT
Remko Popma created LOG4J2-1296:
-----------------------------------

             Summary: Add MessageFactory that reuses a cached Message instance
                 Key: LOG4J2-1296
                 URL: https://issues.apache.org/jira/browse/LOG4J2-1296
             Project: Log4j 2
          Issue Type: New Feature
          Components: API
    Affects Versions: 2.5
            Reporter: Remko Popma
            Assignee: Remko Popma


As discussed in LOG4J2-1270, all current MessageFactory implementations create new temporary
Message objects. A GC-free configuration needs a different MessageFactory that reuses Message
instances.

When Messages are being reused, async logging components need to be aware of this and ensure
the Message _content_  (rather than the Message instance itself) is passed to the background
thread. However, Messages that are not reusable should be passed to the background thread
unchanged.
