    The web application [XXXX] created a ThreadLocal with  key of type
    [net.jawr.web.context.ThreadLocalJawrContext$1]  (value
    [net.jawr.web.context.ThreadLocalJawrContext$1@7c709f7a]) and  a value
    of type [net.jawr.web.context.JawrContext]  (value
    [net.jawr.web.context.JawrContext@45f64269]) but failed to remove it
