This didn't really answer my question. Are you using additional options
beyond what is normally used? If so, then it is unlikely anyone would have
seen these before or investigated and would explain why Jenkins isn't
seeing them either. You'd need to file an issue[1] attaching the log, and
then it will go into the queue to be looked at.
