Examples of javax.enterprise.inject.AmbiguousResolutionException

javax.enterprise.inject.AmbiguousResolutionException
When an injection {@link javax.enterprise.inject.spi.BeanManager#getInstance Manager.getInstance} call cannot return a unique bean, it throwsthis exception. This ambiguity may occur when two subtypes match, e.g. BeanA and BeanB both implementing @Current BeanAPI. The ambiguity may also occur when using more than one {@link javax.enterprise.inject.BindingType @BindingType} on the samebean or when using the special {@link javax.enterprise.inject.Any @Any}bindings, for example:
```
@Foo @A public class Bean {}
@Foo @B public class Bean {}class MyClass {
@Foo Bean _fooField
@Any Bean _anyField} 
```


    private <T> Bean<T> resolveUniqueBean(Type type, Set<Bean<T>> beans) {
        if (beans.size() == 0) {
            throw new UnsatisfiedResolutionException("Unable to resolve any beans of " + type);
        } else if (beans.size() > 1) {
            throw new AmbiguousResolutionException("More than one bean available (" + beans + ")");
        }
        return beans.iterator().next();
