aop - Behaviours of new constructor added by AspectJ ITD -

i applying aspectj our project, , found behavior bit strange me.

q1: added new constructor current class inter-type declaration, , found class's member variable not initialized if new constructor used instantiate class.

for example:

the class i'll add new constructor to:

public class child {      public string name = "john";      public child(string desc) {         // todo auto-generated constructor stub     } }  

the aspectj code:

public aspect mytest {     public child.new(string desc, int num) {         system.out.println("child name:" + this.name);     } } 

if instantiate child new constructor:

new child("a child", 5) 

the member variable this.name not initialized done original constructor.

but, if call original constructor:

new child("a child")  

the member variable this.name initialized "john" usual

the result:

child name:null

is limitation of aspectj? there anyway resolve issue?

i don't want add code member variable initialization new constructor.

q2: seems in newly added constructor, super.method() can not correctly resolved.

the class i'll add new constructor to:

public class child extends parent{      public string name = "john";      public child(string desc) {      } }  

child extends parent. parent has method init()

public class parent {      public void init() {         //....     }  } 

i add new constructor child in aspect.

public aspect mytest {     public child.new(string desc, int num) {         super.init();     } } 

the above aspect code trigger exception.

exception in thread "main" java.lang.nosuchmethoderror: com.test2.child.ajc$superdispatch$com_test2_child$init()v     @ mytest.ajc$postinterconstructor$mytest$com_test2_child(mytest.aj:19)     @ com.test2.child.<init>(child.java:1)     @ mainprogram.main(mainprogram.java:11) 

my workaround define another method class child, , indirectly call super.method() within method

for example, add new method calls super.init() child

public void child.initstate() {     super.init(); } 

now, can call initstate() in newly added constructor below:

public aspect mytest {     public child.new(string desc, int num) {         this.initstate();     } } 

is limitation of aspectj? way resolve issue?

thank time :)

for second question, think it's bug of aspectj. decompile woven target byte code find method “com.test2.child.ajc$superdispatch$com_test2_child$init()v” inserted. implies method should generate aspectj, there no such method in byte code.
