Can not bind multiple interfaces to the same class #349

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
I am using Guice 1.0, sample code is attached.

It runs if you bind InterfaceB to Impl2 instead of Impl.

It produces the following output:

Yikes. Our circular dependency management needs some love.

Committed the test case in r935.
