ClassCastException: com.sun.proxy.$Proxy11 cannot be cast to javax.inject.Provider

Hello there,

We created a binding using toProvider()

bind(ProvidedClass.class).annotatedWith(Names.named("providedClass")).toProvider(ClassProvider.class).in(Singleton.class);

While creating Injector the following error happens:

java.lang.ClassCastException: com.sun.proxy.$Proxy11 cannot be cast to javax.inject.Provider
at com.google.inject.internal.BoundProviderFactory.get(BoundProviderFactory.java:60)

What is wrong with it?

I also tried to get class instance through:

ProvidedClass providedClass = injector.getInstance(Key.get(ProvidedClass.class, Names.named("providedClass")));

but getting the same exception.

I will appreciate any suggestion.

Thanks
Krys
