SEVERE: The web application [/oozie] created a ThreadLocal with key of type [java.lang.ThreadLocal] (value [java.lang.ThreadLocal@7d522180]) and a value of type [org.apache.derby.iapi.services.context.ContextManager] (value [org.apache.derby.iapi.services.context.ContextManager@4a058df8]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.
