Constructor Instrumentation : super()

Hi,
	I have a query regarding the instrumentation of the
constructor. I have read all the archived mail in this
regard, but none of them served useful. I have the
same requirement i.e. put a method call at each method
start and method end. Have already put a try catch for
that. Now the task is to skip super() call before I
put my method call in the constructor.
	
	I have a code that works for 99% of the cases. 
	
	for(int j = 1; j < ihs.length; j++)
	{
		if(ihs[j].getInstruction() instanceof INVOKESPECIAL)
		{
			il.append(ihs[j], instrumentedPatchList);
			break;
		}
	}
	
	It works for 
	
	1)public ABCD(XYZ obj)
	{
		super(obj);
	}
	
	Now a more complicated case
	
	2)public RuleTree(int type, AppCodeAnalyzerMainPanel
mainPanel)
	{
		super(new DefaultTreeModel(new RuleNode("Rules")));
		method1();
		method2();
	}
	
	The above code fails because the Special Instruction
is not at first position. Hence A refined approach
will be to get the first instruction handle of the
second line in the constructor (first instruction
handle for method1()). Now I scan all the instructions
of the first line (super(new DefaultTreeModel(new
RuleNode("Rules")))). If there is any INVOKESPECIAL in
this list I put my code at the end of first line. This
thing works fine.
	
	A bit more complex case
	
	3)private XYZHandler(EventHandler commandHandler)
	{
		super(
			ABCD.getInstance(),
			Helper.getInstance(),
			commandHandler,
			100);
		method1();
	}
	
	Now the above mentioned approach doesn't work and I
end up putting my method call before super() and get
VerifyError. Has anyone (especially the ones who have
posted those questions on constructor instrumentation
previously) been able to build a fullproof code?
	
Thanks,
	Nikhil Khedkar
