Hi All,

I have a few classes ( in a supplied jar) in which I am trying to mark certain specifc methods as "Deprecated" .

I am able to use javassist and add the annotation to the method (code attached to the end of this mail) but Eclipse refuses to identify that as a "Deprecated" method at compile time.

I decompiled and verified that there is a "@Deprecated" annotation on the method. I also used ASM compare between a class in which I added a @Deprecated and this class in which javassist  added the annotation and notice one strange thing : the access flags are different

"normal" method :

// DEPRECATED

  // access flags 0x20001

  public getName()Ljava/lang/String;

  @Ljava/lang/Deprecated;()

   L0

    LINENUMBER 7 L0

javassist annotated method :

   // access flags 0x1

  public getName()Ljava/lang/String;

  @Ljava/lang/Deprecated;()

   L0

    LINENUMBER 7 L0

Questions :

1) is there a problem in the way the Annotation is being added ?

2) Cant I add a java.lang.Deprecated annotation to a method ? is there some special modifier or instruction to be used to add the inbuilt java Annotations ?

Any help or pointer is appreciated !!

I tried to make it a "invisibleTag" ,  specify it as "Deprecated" , "@Deprecated" but the IDE refuses to treat that as a Deprecated API.

thanks

Pat

CtMethod[] methods = cc.getMethods();
  for (int k = 0; k < methods.length; k++) {
   CtMethod met = methods[k];
    System.out.println("Found Method --> " + met.getName());
    try{
     ClassFile ccFile = cc.getClassFile();
     ConstPool constpool = ccFile.getConstPool();
    
     AnnotationsAttribute attr = new AnnotationsAttribute(constpool, AnnotationsAttribute.visibleTag);
     Annotation annot = new Annotation("java.lang.Deprecated", constpool);
     attr.addAnnotation(annot);
     met.getMethodInfo().addAttribute(attr); 
    
    
    }catch(Exception e){
     System.out.println("Skipping method:-->" + met.getName() +"Reason:" + e.getMessage() );
    }
