我们正在使用dagger 2.0绑定我们应用中的模块。虽然我们使用guice 3.0设置测试，但到目前为止所有工作都正常，直到我在使用的类中添加了新的方法绑定，并且作为参数我使用：
Optional<Set<DataGroup>> dataGroups
我的代码中的类似于：
@Inject
public void setDataGroups(@Named(DATA_GROUPS) Optional<Set<DataGroup>>
dataGroups) {
this.dataGroups = dataGroups;
}
在我使用guice的测试模块中，我用这种方式绑定这些数据组：
Optional<Set<DataGroup>> dataGroups = Optional.of((new HashSet<DataGroup>());
bind(new TypeLiteral<Optional<Set<DataGroup>>>() {
}).toInstance(dataGroups);
它不起作用。通过运行测试我得到：
com.google.inject.internal.util.$ComputationException: java.lang.ArrayIndexOutOfBoundsException
如果我通过提供List接口（当然还有更改dataGroups字段的声明）在代码中实现我的setDataGroups（）方法，这很奇怪，而且一切正常：
@Inject
public void setDataGroups(@Named(DATA_GROUPS) Optional<List<DataGroup>>
dataGroups) {
this.dataGroups = dataGroups;
}
和guice中的测试模块中的绑定：
Optional<List<DataGroup>> dataGroups = Optional.of(new ArrayList<DataGroup>());
bind(new TypeLiteral<Optional<List<DataGroup>>>() {
}).toInstance(dataGroups);
所以我想知道绑定Set和List之间是否有什么特别之处，因为我找不到任何线索为什么设置Set接口在guice中不起作用并且打破测试模块
我尝试使用guice 4.0，因为我读到了类似的问题，但是他们触摸lambdas而不是使用HashSet实例绑定Set接口。
提前致谢。
