---------------------------------------

             Summary: Allocation regression in simple log invocation
                 Key: LOG4J2-2626
                 URL: https://issues.apache.org/jira/browse/LOG4J2-2626
             Project: Log4j 2
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.11.2
            Reporter: Gilad Bar Orion


A simple _log.info("something")_ appears to cause allocation in 2.11.2.

Same code in 2.10.0 cause no such allocation.
