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

             Summary: No Server logs after shutdownHook has been called
                 Key: ISPN-11485
                 URL: https://issues.redhat.com/browse/ISPN-11485
             Project: Infinispan
          Issue Type: Bug
          Components: Server
    Affects Versions: 10.1.5.Final, 11.0.0.Alpha2
            Reporter: Ryan Emerson
            Assignee: Ryan Emerson
             Fix For: 11.0.0.Dev03, 10.1.6.Final


When a server process receives a SIGTERM it simply logs the following, regardless of the log configuration:

{code}
INFO  (Thread-0) [org.infinispan.SERVER] ISPN080002: Infinispan Server stopping
INFO  (Thread-0) [org.infinispan.SERVER] ISPN080002: Infinispan Server stopped
{code}

This is because Log4j registers a shutdownHook with the runtime in order to cleanup log resources. In order to aid server debugging, we should [disable this shutdownHook|https://logging.apache.org/log4j/2.x/manual/configuration.html] and manually shutdown the Log4j LogManager.
