严重: The web application [/SSH] created a ThreadLocal with key of type [com.sun.faces.util.Util$1] (value [[email protected]]) and a value of type [java.util.HashMap] (value [{com.sun.faces.patternCache={ = }}]) 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.
