--------------------------------------------
Summary: Blueprint does not find an argument which uses generics
Key: ARIES-1241
URL: https://issues.apache.org/jira/browse/ARIES-1241
Project: Aries
Issue Type: Bug
Components: Blueprint
Reporter: Jean-Philippe CLEMENT
Let's say an 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 using blueprint fails with the error that no constructor is found matching A.
A workaround is to simply remove generics. Then Blueprint correctly injects A
in B. Another workaround is to correct A definition to X<Component>. Then A can
be injected into B using blueprint.
Java generics is based on type erasure so - once compiled - generics must not
interfere at runtime.
