Matt Sicker commented on LOG4J2-1820:
-------------------------------------
There's a check in LoaderUtil for the getClassLoader permission already. If you
don't have that, then good luck running almost anything that isn't fully custom
code.
With the security check for getting a ClassLoader, the possibility of a
ClassLoader being null (which indicates the root ClassLoader basically), and
various other edge cases, it almost makes me think that this is a class that
needs to be abstracted, though I think it'd probably be overkill.

>
> When Log4j is rendering an exception, it can attempt to access a class loader
> that it does not have permissions to access when a security manager is
> present.
> I have a patch and a failing test case for this; I will submit it shortly.
> This is similar to LOG4J2-1560.
