--------------------------------------------
Hi
Just tested master.
For Java 17 it does not work: `java.lang.IllegalAccessError: Cannot access
field protected org.apache.logging.log4j.plugins.di.Injector
org.apache.logging.log4j.core.selector.ClassLoaderContextSelector.injector`.
On Java 11 I'm around 430ms (vs 45ms for a simple implementation) so looks like
it is still way too slow.

> Project: Log4j 2
> Issue Type: Task
> Components: Core
> Affects Versions: 2.13.0
> Reporter: Romain Manni-Bucau
> Priority: Major

> Currently (2.13), LogManager.getLogger("xxx") takes ~600ms on a cold JVM by
> itself.
> For a logging framework it is likely way too much (by comparison a CDI test
> with classpath scanning takes ~50ms).
>
> This ticket is about trying to be faster (maybe by removing java
> serialization usage and reducing registry usage + reflection of plugins by
> generating java code?).
