VerifyError with addLocalVariable() and insertAfter()
-----------------------------------------------------

                 Key: JASSIST-93
                 URL: https://jira.jboss.org/jira/browse/JASSIST-93
             Project: Javassist
          Issue Type: Bug
         Environment: javassist 3.11 and 3.5
JDK6
 
            Reporter: Joerg Plewe

Hi all!

This is my first post here and I am a javassist newbie. So hopefully my problem can easily be solved.

>From a real usecase, I condensed the following fragment demonstrating my problem:

Code:

ClassPool cp = ClassPool.getDefault();
CtClass cl = cp.getCtClass("jatest.Test");
CtMethod m = cl.getDeclaredMethod("foo");

m.addLocalVariable("bar", CtClass.longType);
m.insertAfter("bar;", true);

Object o = cl.toClass().newInstance();	



The class 'Test' is as simple as it can get:

Code:

public class Test {
	public void foo() {}
}
	



Running the code delivers a VerifyError which I think it shouldn't:

Code:

Exception in thread "main" java.lang.VerifyError: (class: jatest/Test, method: foo signature: ()V) Register pair 1/2 contains 
wrong type
