[Help]How to upgrade my Flowscript code

[lingerer huang]

HI,cocooners:
    After cocoon 2.1.10 release,the js_rhino is alse change.I found this
change break many my flowscript code.I want to upgrade my code to make it
run well under 2.1.10 and versions before 2.1.10.I need some help to
complete it.
    1.Exception
        In 2.1.9,I can do this:
        try{
                ....
        }catch(e){
                myexceptionProcessor.process(e);
        }
        this wouldn't work in 2.1.10 because e is not Exception now ,it is
org.mozilla.javascript.NativeError now.
       Questions:
        How can I judge whether e is a Exception or NativeError?
        If e is NativeError,how can I get the original Exception?

    2.Class cast in Java
      In 2.1.9 I can do this in Java:
        myobj = (MyClass) cocoon.jsFunction_getComponent(MyClass.ROLE);
      In 2.1.10 the return is org.mozilla.javascript.NativeJavaObject
      Questions:
        How can I get the original Object?

Thanks.
