[cdi-dev] Lifecycle Callback Interceptor and @Target "METHOD"

[Martin Kouba]

Hi Radim,

no, adding @AroundConstruct callback does not help. The statement Jozef
is referencing means: An interceptor for @PostConstruct and @PreDestroy
lifecycle callbacks may only declare interceptor binding types that are
defined as Target(TYPE). The PerformanceInterceptor declares
@PostConstruct callback and that's why the @Measure interceptor binding
has to defined as Target(TYPE).
