[jira] [Updated] (KARAF-2352) Blueprint does not find a bean argument which uses generics

     [ https://issues.apache.org/jira/browse/KARAF-2352?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jean-Philippe CLEMENT updated KARAF-2352:
-----------------------------------------

    Description: 
Interface X<T> is defined.
A class A implements X<JPanel>.
Another class B has a constructor with a single argument X<? extends Component>.

Calling B with A using regular Java code is correct. However, injecting A with B fails with the error that no constructor is found matching A. Even type forcing fails.

If I correct A definition to X<Component> then A can be injected into B.

  was:
Interface X<T> is defined.
A class A implements X<JPanel>.
Another class B has a constructor with a single argument X<? extends Component>.

In Java calling B with A is correct. However, injecting A with B fails with the error that no constructor is found matching A. Even type forcing fails.

If I correct A definition to X<Component> then A can be injected into B.
