Of course, as many have done, I've run Java applications with JFR
enabled using these options against this very JVM (jdk1.8.0_112). So, it
isn't a problem for the JVM I'm using. I haven't finished digging down
into ProcessBuilder, or deeper, to figure out why these options are not
getting love. I'll get back at it tomorrow and report back.

In the end, NiFi's grumpy about this and won't start (from
/logs/nifi-bootstrap.log/):

I tried using all options as one (in case the order is disturbed,
which it was):
java.arg.15=-XX:+UnlockCommercialFeatures-XX:+FlightRecorder-XX:StartFlightRecording=duration=120m,filename=recording.jfr
and then I get:

Here's the second command line from /logs/nifi-bootstrap.log/, which
I've wrapped for convenience in reading (see JVM version here too):

Last, I frantically tried this:
java.arg.15="-XX:+UnlockCommercialFeatures -XX:+FlightRecorder
-XX:StartFlightRecording=duration=120m,filename=recording.jfr"
and then got:
*2016-12-14 11:01:36,659 ERROR [NiFi logging handler]
org.apache.nifi.StdErr Error: Could not find or load main class
"-XX:+UnlockCommercialFeatures -XX:+FlightRecorder
-XX:StartFlightRecording=duration=120m,filename=recording.jfr"*
What's the canonical way of adding/inserting my own JVM commands?
Alternatively, is NiFi analyzing and blocking -XX:arguments to the JVM
as illegal or unrecognized?
Thanks,
Russ
