[jira] Commented: (ARIES-82) BeanRecipe fails when using generics
Posted by "Oliver Lietz (JIRA)" <ji...@apache.org>.

Oliver Lietz commented on ARIES-82:
-----------------------------------
package org.springframework.beans.factory;
public interface FactoryBean<T> {
T getObject() throws Exception;
Class<? extends T> getObjectType();
boolean isSingleton();
}
It's "T getObject()" in Spring 3.0. So, is this intended behavior? It looks wrong to me.

[jira] Commented: (ARIES-82) BeanRecipe fails when using generics
Posted by "Valentin Mahrwald (JIRA)" <ji...@apache.org>.

Valentin Mahrwald commented on ARIES-82:
----------------------------------------
What seems to happen is that the Java compiler creates a synthetic bridge method "Object getObject" that bridges between the getObject declared in FactoryBean (Object getObject()) and the one implemented in SpringFactoryBean (Spring getObject()).
Blueprint finds both these methods and throws it hands up, where it should probably filter out synthetic / bridge methods, which would give a unique result.

[jira] Commented: (ARIES-82) BeanRecipe fails when using generics
Posted by "Jeremy Hughes (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/ARIES-82?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12790372#action_12790372 ]
Jeremy Hughes commented on ARIES-82:
------------------------------------
I suspect this is because the FactoryBean interface defines an "Object getObject()" method and SpringFactoryBean implements a "Spring getObject()". It looks like Aries Blueprint is finding both the interface method and the impl method on SpringFactoryBean and treating them as different.

Thanks, Valentin. Adding mth.isSynthetic() in findMatchingMethods fixed it.
