[jira] [Commented] (ARIES-1674) Multiple inharitance levels with generics cause ClassCastException when JPA is enabled

["Christian Schneider (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARIES-1674?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15875862#comment-15875862 ] 

Christian Schneider commented on ARIES-1674:
--------------------------------------------

I was not able to build your project. I got this exception:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-install-plugin:2.5.2:install (default-install) on project features: Failed to install artifact org.broken:features:xml:datasource:1.0-SNAPSHOT: /home/cschneider/checkout/inheritance/features/src/main/java/../resources/datasource-h2.xml (No such file or directory) -> [Help 1]

Can you give some more information about the ClassCastException you see?

> I'm using inheritance with generics over multiple levels.
> Injecting properties to those beans works fine, but on access of a property of the lowest class, there is a ClassCastException thrown.
> I could narrow it down to enabling JPA in the blueprint causing the issue:
> When disabling JPA, the proper bean class is resolved,
> enabled the type resolving stopped at the parent abstract class of the expected class, thus throwing a ClassCastException.
> Example project to reproduce this issue:
