Maxime, You wrote, WDIT? I think that IntStack.java has almost no economic value and so the comparison to a commercial package is not really appropriate. We could ask upstream (file a bug report) but the question is pretty awkward. We are not asking for a bug fix, or for clarification of a behaviour. We are questioning if they are meeting their own stated licensing criteria! Besides that such a ticket is very difficult to resolve. I would feel bad asking this of them because I imagine they are no better equipped to answer questions about JDK1.0 than we are. Worse, if we believe such impropriety is possible why would be believe what they tell us anyway? I think to ask for this to be investigated, at minimum, you would need to find the actual file from JDK1.0 that you feel was appropriated. I don't think we should be asking upstream to work on investigation of a suspicious licensing that cannot improve their software in any functional way. I appreciate your keen sensitivity to the code but I don't think this feedback to apache is helpful and is likely not even true.
