Function importPackage must be called with a package; had "[JavaClass java.util.ArrayList]"

Java调用JavaScript时，若出现这个异常信息，是由于javascript文件中到导包不正确，将导包：
importPackage(java.util.ArrayList);改成 importPackage(java.util); 

Function importPackage must be called with a package; had "[JavaClass java.util.ArrayList]" instead
