Hi Jochen,
to query for the correct result you can just use a Key based on the correct
TypeLiteral for the multi bound instances.
In your example this would be:
Set<LifecycleAware> lifecycleAwares = pInjector.getInstance(Key.get(new
TypeLiteral<Set<LifecycleAware>>(){}));
If your getLifecycleAwares() method really needs to be a List instead of a
Set, you need to wrap/copy the retrieved Set, e.g. through Guavas
ImmutableList.copyOf(lifecycleAwares) or something similar.
Regards,
Johannes
