use of io.micronaut.aop.Around in project helidon by oracle.

the class MicronautCdiExtension method processTypes.

 * In case a Micronaut bean definition is available for the CDI bean (which should be for application, as
 * the CDI annotation processor should be used, and it adds CDI beans as Micronaut beans), the information
 * is combined from Micronaut and CDI bean definitions.
