---------------------------------
Assignee: Freeman Fang
> NullPointer exception when interface contains generics
> ------------------------------------------------------
>
> Key: CXF-3527
> URL: https://issues.apache.org/jira/browse/CXF-3527
> Project: CXF
> Issue Type: Bug
> Components: Aegis Databinding
> Affects Versions: 2.3.3
> Environment: Debian GNU/Linux Tomcat6
> Reporter: Vassilis Virvilis
> Assignee: Freeman Fang
>
> The following code fails with a NULL pointer exception in deploy. Always the
> same. In order to reproduce the problem you have to uncomment the method
> declarations otherwise the war does not deploy.
> What I would like in case it is not possible to make it work in Aegis due to
> other constraints is a better error mentioning the problematic method because
> right now I have to suspect all methods and play binary search to find the
> problematic ones.
> // fails with null pointer exception in deploy
> // public T testGeneric(Collection<T> collection);
> // success
> public Integer testGeneric(Collection<T> collection);
> // fails with null pointer exception in deploy
> // public <T1, T2> Pair<T1, T2> testReturnGenericPair(T1 first, T2
> second);
> // fails with null pointer exception in deploy
> // public Pair<Integer, String> testReturnQualifiedPair(Integer first,
> // String second);
> // fails with null pointer exception in deploy
> // public <T1, T2> int testGenericPair(Pair<T1, T2> pair);
> // fails with null pointer exception in deploy
> // public int testQualifiedPair(Pair<Integer, String> pair);
