ping cheng updated LOG4J2-1729:
-------------------------------
Description:
1. There is two classloder. Parent and Child.
2. Log4j*.jar is loaded by Parent and log4j2.xml is loaded by Child.
3. The class using log4j is loaded by child.
4. The threadContextClassLoader is child.
5. Using "evaluateOnStartup" and the log need rollover on startup.
Reason:
Threre creat two LoggerContext. And two context load one config ,all need to
rollover the log.
