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

This issue is marked resolved as it relates to the bug in what Matt 
implemented. Matt's code is going to be removed and replaced with something 
else. So LOG4J2-3341 really needs to be reopened.

[~mattsicker] After you revert the change for LOG4J2-3341 I will look into 
adding the support as a "normal" property that simply performs two different 
actions. it does mean that if you do


{code:java}
rootLogger=${sys:root.logger:-INFO,console} {code}
and then define the root.logger system property as something like:
{code:java}
${sys:log.level:-INFO}, console
{code}
The log level info replacement will not occur. Instead, it will get an error 
when it tries to set the level to "${sys:log.level:-INFO}".
