             Summary: SimpleProcessLogger substitutes the "Object[] + Throwable" arguments incorrectly
                 Key: NIFI-11628
                 URL: https://issues.apache.org/jira/browse/NIFI-11628
             Project: Apache NiFi
          Issue Type: Bug
            Reporter: Peter Turcsanyi
            Assignee: Peter Turcsanyi


{{SimpleProcessLogger}} substitutes the log message arguments incorrectly when the {{Object[] + Throwable}} signature is used.

The Object[] (containing the log message arguments) is treated as a single argument and the whole array is replaced in the first {} placeholder, while the remaining {} placeholders stay unresolved.

Incorrect:
