Currently, there is an issue when the method
from VisitorsBridgeForTests.TestJavaFileScannerContext class is executed and the "secondary" parameter is not an empty List.
Consequently, instead of creating secondaries (a list of list of a single elements), we are then creating a singleton list containing a single list with all the elements, which is then considered as being a flow. This make tests of secondaries impossible in this context.
The "secondaries" parameter should be a changed before provided to the next layer, and translated into a List that contains a SingletonList for each Location object.
