Description
Thread local 'currentLogEvent' is not cleaned on shutdown which prevent web applications clean undeploying.
Tomcat prints following:
SEVERE: The web application [/web] created a ThreadLocal with key of type [java.lang.ThreadLocal] (value [java.lang.ThreadLocal@22410487]) and a value of type [org.apache.logging.log4j.core.impl.Log4jLogEvent] (value [Logger=********* Level=INFO Message=************]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.
We use async loggers declared explicitly in log4j2.xml:
<AsyncLogger name="logger" additivity="false" level="trace"> ......
We use RollingRandomAccessFile as appender.
