update javassist to 3.18.2-GA or higher

[csokol]

Apparently java 8 lambdas are incompatible with javassist. I have a project with vraptor-3.5.3 and when I add a lambda in my code, javassist throws an exception.

For example:

@Resource
public class FooController {
    public void bar() {
        List<Integer> list = Arrays.asList("oi").stream().map((s) -> s.length()).collect(Collectors.toList());
        System.out.println(list);
        result.nothing();
    }
}

VRaptor throws the following exception: https://gist.github.com/csokol/3de6fb450689ff3c3660

Any ideas?

It's related to scanannotation, so it shouldn't affect vraptor 4, right? Maybe we should consider using reflections project (http://code.google.com/p/reflections/) to do the scanning, since scanannotation development is dead.

@csokol if I'm not wrong, this works using javassist 3.18.2-GA or latest, right?

Hi Turini, I haven't used vraptor 3 since a long time, but I guess it looks
like it is a javassist incompatibility indeed.

Are we already forcing vraptor 3 to use this newer version of javassist? If
we are, then I think we can close this issue.

humm, we don't (https://github.com/caelum/vraptor/blob/master/vraptor-core/pom.xml#L29)
I'm updating issue title, to just update and test with latest javassist version. Thanks @csokol
