You should ask on https://groups.google.com/d/forum/google-gin as the GWT
Compiler is not involved in these decisions, only the GIN generator.
BTW, what's the error? Does it work if you don't use an AsyncProvider?
(direct injection, or through a Provider)
And as a workaround / alternative, I suppose you could use a "@Special
Provider<DiSecondary>" and an explicit GWT.runAsync.
