I have an interface with two classes implementing it. I tried to use a List to inject all the implementations in it. But I got a WELD exception.
Earlier I used javax.enterprise.inject.Instance and all implementations were injected properly.
I just wondered what if javax.enterprise.inject.Instance is not there and how can I solve my problem so I did this experiment.
Below is the stack trace

We have different implementations for an interface and at runtime we want to resolve which one to use. So we used javax.enterprise.inject.Instance. We pass a custom annotation to the select method of Instance and returns the appropriate implementation. The implementation are annotated with the custom annotation. This is how we are injecting all instances and using the appropriate instance. Below is a sample snippet
@Inject
@Any
private Instance<SoftwarePackageDescriptorProvider> descriptorProviders;
descriptorProviders.select(new PlatformQualifier(platformType)).get();
Not sure if there is a way to get a dynamic list of all implementation classes, but you could use a qualifier, to say which specific class you want:
