Assisted injection of inherited specialized interfaces fails

[GoogleCodeExporter]

Hi,

let's say the following code :

package guice.test;

import com.google.inject.*;
import com.google.inject.assistedinject.*;

class Parent { @Inject Parent(@Assisted Object o) {} }
class Child extends Parent { @Inject Child(@Assisted Object o) { super(o); } }

interface ParentFactory { Parent create(Object o); }
interface ChildFactory extends ParentFactory { @Override Child
create(Object o); }

public class Test {
    public static void main(String[] args) {
        Guice.createInjector(new AbstractModule() {
            @Override protected void configure() {

bind(ChildFactory.class).toProvider(FactoryProvider.newFactory(ChildFactory.clas
s,
Child.class));
            }
        });
    }
}

Here is the stacktrace I found:

Exception in thread "main" java.lang.IllegalAccessError: tried to access
class com.google.inject.ConfigurationException from class

    at com.google.inject.Guice.createInjector(Guice.java:43)
    at guice.test.Test.main(Test.java:14)

It is failing for two reasons.
1. The newConfiguration fails for the reason mentionned in the stacktrace
above.
2. The newConfiguration is called because there are more "create" methods
than constructors. In absolute, that is right, because there is one
constructor and two create methods, but the two methods of the factory have
the exact same signature (but not the same return type), meaning that the
method of ChildFactory overrides the method of ParentFactory, and this
exception should not be raised in this case, because there is only one
actual constructor and only one actual "create" method.

I was not aware that there was a recent snapshot (2009/2/5). These bugs are 
fixed in
that new version!
