---------------------------------
Summary: Log4j2 Incorrectly Uses System Property For Level Setting
And Got IllegalArgumentException
Key: LOG4J2-3413
URL: https://issues.apache.org/jira/browse/LOG4J2-3413
Project: Log4j 2
Issue Type: Bug
Components: Configuration
Affects Versions: 2.17.1
Environment: IBM WAS 9, JAVA 8
Reporter: Sean Wang
Attachments: Log4j2IssueLogs.txt
We have an environment parameter in IBM WAS 9 running JAVA 8 with a name of
"level" and a value of "DEVL". This parameter is used by applications to
detect the environment they are on and worked fine with log4j1.x.
After upgraded to Log4j2.17.1, for some reason the Log4j2 grabs that parameter
during the initialization, ignoring the settings in the log4j2.xml, and spills
a _java.lang.IllegalArgumentException: Unknown level constant [DEVL]_ in the
system log.
