To reproduce, take the test case attached to OWB-1065 and uncomment a line in
the {{Sender}} class:
{code}
public void onInitialized(@Observes @Initialized(ApplicationScoped.class)
Object object) {
List<Integer> list = new ArrayList<>(Arrays.asList(1, 4, 9, 16));
list = Arrays.asList(1, 4, 9, 16);
event.fire(list);
}
{code}
