No, it doesn't happen with jlc, only with Soot. I suspect it may have
something to do with the fact that in Soot, A is not an application
class and doesn't get resolved all the way through (it's not written
out). Both Polyglot on its own and Abc force A to be an "application
class": Abc gives an error if you don't explicitly specify it, while
Polyglot silently adds it for you to the list of classes to be compiled.
