[jira] [Commented] (FELIX-1017) Generic types ignored when generating MANIFEST.MF

------------------------------

Hi Stuart,

what exactly did you fix with last upgrade 0.0.357?

We have a similar issue and I'd like to hear your opinion. 
Shortened scenario:
Project with a service-api-module with pom that tells felix to create a MANIFEST.MF because we also use it in an Eclipse / equinox environment.
Felix omits import-package for a certain class 'Type' because no bytecode usage - (generic<Type>) erased.
Client fails to start because (a little bit complicated): Spring Bean creation there checks via org.aspectj.weaver.reflect... the generic type that it thinks it needs 'Type'.

My questions are: 
Is this fixed with your upgrade?
Is this more a bug of Spring checking too much?
We currently use a work-around declaring "Import-Package: Type" directly which is a little bit unsatisfactory since it could happen again any time and this 'bug' was hard to find.

Best regards,
Chris

> Generic information present in the bytecode is not considered when MANIFEST.MF is generated. In the following example, the package "a" is not included in the Import-Package list, which causes an Exception at runtime (TypeNotPresentException)
> package b;
> import java.lang.reflect.*;
> import a.A;
> public class B {
>     java.util.List<A> list;
>     public static void main(String[] args) {
>        for(Field f : B.class.getDeclaredFields()) {
>            ParameterizedType type = (ParameterizedType)f.getGenericType();
>            for(Type t : type.getActualTypeArguments()) {
>                System.out.println(t); // <--- java.lang.TypeNotPresentException: Type a.A not present
