Summary

0004512: IllegalStateException for stateless session bean implementing generic interface

Description

Given the following hierarchy:

interface Importer<T>
interface StringImporter extends Importer<String>
@Stateless class StringImporterImpl implements StringImporter

The Importer<T> interface defines a generic method: void doImport(T t)

For the stateless bean, Resin tries to generate a proxy class and fails with the following message:
java.lang.IllegalStateException: AnnotatedMethodImpl[public abstract void bugreport.beans.Importer.doImport(java.lang.Object)] does not have a matching base method in AnnotatedTypeImpl[class bugreport.beans.StringImporterImpl]

It seems that the generic type on method level is misinterpreted when generating the proxy class. Instead of String, java.lang.Object is taken as argument.

Note: This issue is a more detailed variant of bug 0004467. Enclosed you find an example maven project which reproduces the bug. A patch (inevidently just a workaround) is provided in bug 0004467.

Additional Information

Full stack trace:

java.lang.IllegalStateException: AnnotatedMethodImpl[public abstract void bugreport.beans.Importer.doImport(java.lang.Object)] does not have a matching base method in AnnotatedTypeImpl[class bugreport.beans.StringImporterImpl]
