Multibinder doesn't handler circular references

Shouldn't the attached test case work without having to use a Provider? I get this exception:

1) Error in custom provider, java.lang.IllegalStateException: This is a proxy used to support circular references involving constructors. The object we're proxying is not constructed yet. Please wait until after injection has completed to use this object.
