Right. So i think the short version is in the UI now. But you want the
stacktrace too. We should make that available in the logs. And this class is
what controls that I believe
https://github.com/apache/nifi/blob/master/nifi-commons/nifi-logging-utils/src/main/java/org/apache/nifi/logging/NiFiLog.java
You'll see it has some ifDebugEnabled guards. We should probably just toss
those out. @markap14 what say you?
