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} 
```

    {
        violationMessage.addLine("found beans: ");


        addBeanInfo(beans, violationMessage);


        throw new AmbiguousResolutionException(violationMessage.toString());
    }
