SEVERE: The web application [/cms] created a ThreadLocal with key of type [org.jgroups.protocols.FlowControl$1] (value [org.jgroups.protocols.FlowControl$1 at 536c4bc7]) and a value of type [java.lang.Boolean] (value [false]) 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.
