-----------------------------------------
I just checked the logs of my appache server, and it's logging next info, what
is the cause of this?

org.apache.catalina.loader.WebappClassLoaderBase.checkThreadLocalMapForLeaks
The web application [coliseum_agency] created a ThreadLocal with key of type
[java.lang.ThreadLocal] (value [java.lang.ThreadLocal@22427e45]) and a value of
type [org.apache.logging.log4j.spi.MutableThreadContextStack] (value [[]]) 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.
