Github user cestella commented on the issue: https://github.com/apache/metron/pull/1093 Ah crap, I misread a stacktrace. It didn't fail to log the full one, I just failed to have reading comprehension. The main issue here was I saw a stack trace in the wild, which i'm not sure I can share, that appeared to cut off the trace AT the point of a NPE but without the full stack trace of the NPE, which made diagnosing it impossible. I see now that I just didn't get the full cut and paste. I'm closing this.
