-------------------------------------

             Summary: When looking up a mandatory bean, look it up through its type first
                 Key: CAMEL-19234
                 URL: https://issues.apache.org/jira/browse/CAMEL-19234
             Project: Camel
          Issue Type: Bug
          Components: camel-core
    Affects Versions: 3.0.0-M3
            Reporter: Marco Bungart


Currently, when we look up a mandatory bean which type we know, we perform the lookup with the bean's name and convert it to the requested type:

public static <T> T mandatoryLookupAndConvert(CamelContext context, String name, Class<T> beanType) {
    Object value = lookup(context, name);
    if (value == null)

{         throw new NoSuchBeanException(name, beanType.getName());     }

    return convertTo(context, beanType, value);
}

Source: [https://github.com/apache/camel/blob/main/core/camel-support/src/main/java/org/apache/camel/support/CamelContextHelper.java#L245]

This leads to problem with the current implementation of [https://github.com/apache/camel-quarkus/issues/4725,] where we introduced automatic registration of beans annotated with {{@Identifier}} when several beans with the same {{@Identifier("<name>")}} are present. We think we can prevent this problem when we modify above method to do a {{lookup(...)}} with the type information, and only do the {{lookup(...)}} without type information yielded no result.
