Gary Gregory commented on LOG4J2-2171:
--------------------------------------

Tangents:

We also have 
{code:java}
org.apache.logging.log4j.util.LoaderUtil: public static final String 
IGNORE_TCCL_PROPERTY = "log4j.ignoreTCL";
{code}
It seems confusing to also have both {{log4j.ignoreTCL}} and {{log4j.forceTCL}}.

Why is the prop called {{log4j.ignoreTCL}} instead of {{log4j.ignoreTCCL}} BTW? 
Is that a typo?

Why is the prop prefix "log4j" instead of "log4j2"? I thought we had normalized 
on "log4j2"?

Should we have a single "log4j.TCCLStrategy" instead of possibly mutually 
exclusive multiple booleans?


> Log4j2 is not embeddable due to its system classloader usage

> Hi guys,
> in several places, log4j2 enforces the system classloader to be used. I have 
> a case where I isolate a classloader from the app which can have log4j2 and I 
> don't want any leakage between both classloaders.
> This is current not possible. Can we have at least an option to skip this 
> classloader and only use the tccl one?
> For reference: {{org.apache.logging.log4j.util.LoaderUtil#getClassLoaders}}, 
> {{org.apache.logging.log4j.util.LoaderUtil#findUrlResources}}, etc... are the 
> places making it not working
