CastClass exception (NullBean instead of 'null' value) when getting map of beans directly from ApplicationContext [SPR-16163]

[spring-projects-issues]

Francisco Lozano opened SPR-16163 and commented

#20582 was seemingly fixed for 5.0.1 for autowiring, but in that release when asking the app context directly for a map of beans of a given type (getBeansOfType), the problem remains.

Reproduced in spring-attic/spring-framework-issues#173.

And here we go with the fix: it'll be available in the upcoming 5.0.2.BUILD-SNAPSHOT.

Thanks for your efforts in uncovering every corner of this :-)
