Problem Description
the java.util.Map/HashMap only support Object as the root, and AnyRef is the alias of Object. there are many cast between java.util.Map[String, Any] to java.util.Map[String, AnyRef]. Infact in java there is only java.util.Map[String, AnyRef] is worked in memory. so change the define of java.util.Map/HashMap[String, Any] to java.util.Map/HashMap[String, AnyRef] to reduce the unnessary cast.
