Does NiFi Support SQL Server 6.2.2 driver​ ?

[#1]

I have a NiFi controller service setup with following configuration.

Controller gets enabled but any processor based on this gets following error.

Does NiFi support SQL Server 6.2.2.driver ?

2018-02-12 12:01:39,045 WARN [Timer-Driven Process Thread-4] o.a.n.controller.StandardProcessorNode Failed during validation
java.lang.NullPointerException: null

[#2]

Can you share more from the logs around the error you're getting? I am looking for the entire stack trace under that NullPointerException (you might see the phrase "Caused by" in there)

@Matt Burgess Please see attached log.

Is there anything right before or after that? Looking at the code, there was no actual controller service instance passed to the validator, so I suspect something else failed before validation. Having said that, generating a NullPointerException here is a bug that should be fixed.

Also, what version of NiFi are you using, and which processor is using that controller service and generating the above error?

@Matt Burgess Please see attached log.nifi2.txt

HDF - 3.0.1.0

[#6]

How about right before that whole trace? I see another stack trace above it that ends with Thread.java

[#7]

@Matt Burgess Here is more of log.

nifi3log.txt

[#8]

There are no stack traces in nifi3log.txt, I expect the error would be further "up" in the log, right above the one in nifi2.txt. What happens if you disable and renable the controller service?

[#9]

@Matt BurgessIt does not matter which processor I use, any processor that is using this controller is giving same error. I deleted and recreated controller but it is still giving same error.
