The web application [/myweb] created a ThreadLocal with key of type [com.sun.xml.bind.v2.ClassFactory$1]
(value [com.sun.xml.bind.v2.ClassFactory$1@2bd27391]) and a value of type [java.util.WeakHashMap]
(value [{class org.apache.camel.spring.CamelContextFactoryBean=java.lang.ref.WeakReference@5a14b11,

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.
