It looks like tree API is not able to acquire tree from an element in compiled class (not the source code).

Currently, a design limitation is @SharedType and its annotations are retained at SOURCE, so they will not be present in compiled class files, when this is a dependency jar (e.g. a sub maven module), they will be ignored silently during the dependent's compilation/ap.

Is this limitation naturally reasonable? Is there a way to let the client explicitly lift this limitation?
