Martin Kouba commented on CDI-517:
----------------------------------
bq. It's at least fine from a pure Java aspect
Works but it's not recommended and you get a compiler warning.
bq. Also note that returning a ParameterizedType does NOT work in the EE6 RI, nor in
WebSphere and also not in older JBossAS versions.
I don't understand. There is a TCK test (since 1.0.x) for a producer method which
returns a parameterized type:
[
ProducerMethodDefinitionTest#testParameterizedReturnType()|https://github...].
assignability to parameterized required type
--------------------------------------------
Key: CDI-517
URL:
https://issues.jboss.org/browse/CDI-517
Project: CDI Specification Issues
Issue Type: Bug
Components: Resolution
Affects Versions: 1.1.PFD, 1.2.Final
Reporter: Mark Struberg
2 days before the CDI-1.1 spec went PDF the following backward-incomatible change was
made:
{quote}
-A raw bean type is considered assignable to a parameterized required type if the raw
types are identical.
+ A raw bean type is considered assignable to a parameterized required type if the raw
types are identical and all type parameters of the bean type are either unbounded type
variables or java.lang.Object.
{quote}
This breaks a lot of projects and also is also not compatible with the JavaEE6 RI and the
CDI-1.0 RI where this was explicitly allowed.
This is a follow up to CDI-304.
