I have to double-check, but it was not there in NIFI 1.8.0 with the previous
JSch (i upgraded due to a Algorithm negociation issue).
I'm using Oracle JRE :
{code:java}
java version "1.8.0_211"
Java(TM) SE Runtime Environment (build 1.8.0_211-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.211-b12, mixed mode){code}
