Description

SEVERE: The web application [/camel-example-activemq-tomcat] created a ThreadLocal with key of type [org.apache.log4j.helpers.ThreadLocalMap] (value [org.apache.log4j.helpers.ThreadLocalMap@1eb0cd0]) and a value of type [java.util.Hashtable] (value [

{activemq.broker=myBroker}

]) 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.

I got a bit annoyed by this when I was working on a new example for Apache Camel with an embedded AMQ broker. So I am digging into fixing this. Its in the start() method.
