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:

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:

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

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

Exception in thread "main" java.lang.VerifyError: (class: jatest/Test, method: foo signature: ()V) Register pair 1/2 contains wrong type
 at java.lang.Class.getDeclaredConstructors0(Native Method)
 at java.lang.Class.privateGetDeclaredConstructors(Class.java:2389)
 at java.lang.Class.getConstructor0(Class.java:2699)
 at java.lang.Class.newInstance0(Class.java:326)
 at java.lang.Class.newInstance(Class.java:308)
 at jatest.Main.main(Main.java:27)

Tested with 3.11 and 3.5. Where is my fault?

Thank you,
