StackOverflow exception on a code analysis

[jrfaller]

Hi!

When trying to analyze a project of mine I run over a StackOverflow exception. Here is the config:

• old artifact : https://repo1.maven.org/maven2/com/github/gumtreediff/core/2.1.2/core-2.1.2.jar
• new artifact : https://repo1.maven.org/maven2/com/github/gumtreediff/core/3.0.0/core-3.0.0.jar

I think I have managed to devise a test case that reproduces the problem, as follows:

@Test
    public void testStackOverflow() throws Exception {
        JarArchiveComparatorOptions jarArchiveComparatorOptions = new JarArchiveComparatorOptions();
        jarArchiveComparatorOptions.setAccessModifier(AccessModifier.PRIVATE);
        List<JApiClass> jApiClasses = ClassesHelper.compareClasses(jarArchiveComparatorOptions, new ClassesHelper.ClassesGenerator() {
            @Override
            public List<CtClass> createOldClasses(ClassPool classPool) throws Exception {
                CtClass superInterface = CtInterfaceBuilder.create().name("I").addToClassPool(classPool);
                CtMethodBuilder.create().returnType(CtClass.voidType).publicAccess().abstractMethod().name("method").addToClass(superInterface);
                CtClass subClass = CtClassBuilder.create().name("C").implementsInterface(superInterface).addToClassPool(classPool);
                return Arrays.asList(superInterface, subClass);
            }

            @Override
            public List<CtClass> createNewClasses(ClassPool classPool) throws Exception {
                CtClass superInterface = CtInterfaceBuilder.create().name("C").addToClassPool(classPool);
                CtMethodBuilder.create().returnType(CtClass.voidType).publicAccess().abstractMethod().name("method").addToClass(superInterface);
                CtClass subClass = CtClassBuilder.create().name("I").implementsInterface(superInterface).addToClassPool(classPool);
                return Arrays.asList(superInterface, subClass);
            }
        });
        JApiClass jApiClass = getJApiClass(jApiClasses, "I");
        JApiMethod jApiMethod = getJApiMethod(jApiClass.getMethods(), "method");
    }

Cheers!
