NiFi 2.6: java.util.concurrent.ExecutionException

Dear community,

Since updating from NiFi 2.4 to NiFi 2.6, I have been getting the 
following errors:

ERROR
Could not start 
StandardControllerServiceNode[service=MapCacheServer[id=fa3ffa43-0193-1000-1b02-4a4de9da8762], 
name=MapCacheServer, active=true] due to 
java.util.concurrent.ExecutionException: 
java.lang.IllegalStateException: Cannot enable 
StandardControllerServiceNode[service=MapCacheServer[id=fa3ffa43-0193-1000-1b02-4a4de9da8762], 
name=MapCacheServer, active=true] because it is not valid

ERROR
Could not start 
StandardControllerServiceNode[service=SSLContextService[id=b3942123-018b-1000-3507-9ecf751f5bbc], 
name=StandardRestrictedSSLContextService, active=true] due to 
java.util.concurrent.ExecutionException: 
java.lang.IllegalStateException: Cannot enable 
StandardControllerServiceNode[service=SSLContextService[id=b3942123-018b-1000-3507-9ecf751f5bbc], 
name=StandardRestrictedSSLContextService, active=true] because it is not 
valid

I am using Ubuntu 22.04 and Java 21.0.8 (OpenJDK).

Is this a known issue?

Did I forget something when upgrading?
Was there a name change to any class in Java that requires flow.json.gz 
to be adjusted?
Am I overlooking something else?

Does anyone have any advice or ideas?

Regards,
Kay-Uwe

Hi,

Please check the controller services in the NiFi UI to get the details
as to why those controller services are not valid. If I had to guess,
I'd say that this is an unexpected side-effect of the JIRA [1] even
though those changes should not cause such effects. The likely
solution is to manually disable the problematic controller service(s),
fix the corresponding configuration issues, and re-enable the
controller services.

Would love to know what the problems are though... We may have to fix something.

Thanks,
Pierre
