ThreadLocal 内存溢出

用ThreadLocal来包装SimpleDateFormat, stop server的时候会出现下列错误

dLocalMapForLeaks
SEVERE: The web application [/log-view] created a ThreadLocal with key of type [
com.hp.hpsc.logview.service.DirectoryService$1] (value [com.hp.hpsc.logview.serv
ice.DirectoryService$1@dd0feea]) and a value of type [java.text.SimpleDateFormat
] (value [java.text.SimpleDateFormat@e863f5a0]) but failed to remove it when the
 web application was stopped. This is very likely to create a memory leak.


频繁的start,stop 该应用会导致permgen (存放class)内存溢出
