Counter class question

I found out that the Counter class is a package private class and the Transaction class has some public methods of Counter type arg.

Was this a mistake or intentional?

Start by inspecting the Counter and Transaction class declarations and the public methods that expose Counter as an argument. Determine whether the package-private visibility is intentional or an API defect; done means the project has a decided, documented resolution for the mismatch.
