Jozef Hartinger commented on CDI-517:
-------------------------------------
{quote}2 days before the CDI-1.1 spec went PDF{quote}
False. See Martin's comment for details.
{quote}backward-incomatible change was made{quote}
False. CDI 1.0 did not allow this. Therefore, specifying this in CDI 1.1 is backward
compatible from the spec point of view.
{quote}not compatible with the JavaEE6 RI and the CDI-1.0 RI where this was explicitly
allowed.{quote}
False. It was never *explicitly allowed*. It was *implicity* allowed by a bug in CDI RI.
Now to get to your point the usage of "raw references to generic types" (called
simply raw types hereafter) is discouraged by the JLS, supported only to provide
compatibility with legacy pre Java 1.5 code and generates a compiler warning. Therefore,
people should not be using it in the first place. You're right that fixing the Weld
bug caused a few problems here and there where people were still using raw types. This is
unfortunate but hardly anything can be done about it at this point especially given that
this was already dealt with in CDI-304.
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.
