Romain Manni-Bucau commented on LOG4J2-658:
-------------------------------------------
Two comments:
1) SPI: useless IMO since in container you use the container spi to force stop,
not shutdown hook
but
2) it means as I said integrating with all containers => not working out of the
box
so
3) log4j2 is not usable in production whatever soft it is since that's in the
"main" classloader
Doing reflection on the jvm doesnt cost log4j2 a lot and the gain is huge, it
is really less than all we wrote in these comments.
PS: Shutdown hooks are not run in parallel but order is not predictable, that's
the only issue.
> shutdown hook called too early

> Hi
> this issue follow few mail exchanges from the commons list. Here the
> interesting part for log4j2:
> {quote}
> Here what I do (we can move it to another thread since that's 100% log4j2
> related):
> unzip apache-tomee-1.7.0-SNAPSHOT-webprofile.zip &&
> cd apache-tomee-webprofile-1.7.0-SNAPSHOT/ &&
> rm conf/logging.properties &&
> echo 'openejb.log.factory=log4j'>conf/system.properties &&
> cp ~/log4j2.xml conf/log4j2.xml &&
> cp
> ~/.m2/repository/org/apache/logging/log4j/log4j-api/2.0-rc2-SNAPSHOT/log4j-api-2.0-rc2-SNAPSHOT.jar
> lib/ &&
> cp
> ~/.m2/repository/org/apache/logging/log4j/log4j-core/2.0-rc2-SNAPSHOT/log4j-core-2.0-rc2-SNAPSHOT.jar
> lib/ &&
> cp
> ~/.m2/repository/org/apache/logging/log4j/log4j-1.2-api/2.0-rc2-SNAPSHOT/log4j-1.2-api-2.0-rc2-SNAPSHOT.jar
> lib/ &&
> ./bin/catalina.sh
> it makes server starting with log4j2 logs, if you ctrl+c logs are not
> printed. Sure it is cause context is closed too early and then loggers have
> NullConfiguration. (If I debug in java.lang.ApplicationShutdownHooks#runHooks
> to wait all hooks exec it works)
> {quote}
> Basically the issue is that when shutting down with ctrl+C some logs are
> swallowed.
