Injecting wildcard results in compile-time error

[GoogleCodeExporter]

What steps will reproduce the problem?

@Inject
public FooTool(List<Bar<?>> bars) {

We set up  our binding like so:
@Provides
public List<Bar<?>> provideBarList(FooProvider2 f) {
 return f.get();
}

At compile time we get the following exception:

What is the expected output? What do you see instead?
No exception, just injection of what we need

What version of the product are you using? On what operating system?
Default version (r146?)
Goobuntu

This bug still happens in 1.0:

java.lang.IllegalArgumentException: Not enough type arguments were specified to 
parameterize 'java.util.Set<E>'

    at com.google.gwt.dev.javac.StandardGeneratorContext.runGenerator(StandardGeneratorContext.java:427)

Also when I try to bind with a @Named annotation it say's that there's no 
implementation bound.

No implementation bound for key Key[type=java.util.Set>, 
annotation=@com.google.inject.name.Named(value=name_value)]

When I bind this thing as an Object and cast it after it's injected it works 
fine.

Yes, 1.0 was cut a long time ago now, before these fixes. A new release is 
coming up although it's currently blocked on Guice 3.0 being ready (Guice is 
going through RC right now).
