Title: Message Title

Tomasz Krakowiak commented on WELD-1492   Re: Producers with parameterized return types with a nested parameterized type containing a wildcard or type variable are not detected as invalid Are you sure those are definition errors: @Produces Bar<Foo<?>> wildcardFooBarProducerField; @Produces Bar<Foo<?>> produceWildcardFooBar() { ... } ? Is this conclusion based on - CDI 1.1 - 2.2.1 Legal bean types? (http://docs.jboss.org/cdi/spec/1.1/cdi-spec.html#legal_bean_types It say "A parameterized type that contains a wildcard type parameter is not a legal bean type.". But it doesn't say that that wildcards are disallowed on deeper levels of parameterized type parameters. It see it as analogy to: //Illegal java type. MyList extends List<?> { //... }   // Legal java type @ApplicationScoped //Also legal bean type MyList extends List<Optional<?>> { //... } Add Comment   This message was sent by Atlassian JIRA (v6.3.11#6341-sha1:83c4d29)
