-----------------------------------
Hi [~bennyboi],
I do believe we make use of JAVA_HOME. The relevant section is here:
https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-resources/src/main/resources/bin/nifi.sh#L121-L155.
We have no static references to any files in that script. We do make a best
effort if all the normal avenues fail, but that outputs "JAVA_HOME not set;
results may vary" as shown at
https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-resources/src/main/resources/bin/nifi.sh#L138.
This does not seem to be evident in the log you shared with us. I do see you
are running nifi with sudo. Does `sudo jenv versions` also provide the
selected 1.8 version?
Anything in the shared section look amiss to you that we may be overlooking? I
know several folks in the community use jenv on a regular basis (inclusive of
myself) especially as we worked to provide support for building/running on Java
11.

> Key: NIFI-6584
> URL: https://issues.apache.org/jira/browse/NIFI-6584
> Project: Apache NiFi
> Issue Type: Improvement
> Environment: Distributor ID: Ubuntu
> Description: Ubuntu 18.04.3 LTS
> Release: 18.04
> Codename: bionic
> https://github.com/jenv/jenv
> Reporter: Ben Stuart
> Priority: Major
> Fix For: 1.9.1
>
>
> I've been notified NiFi dosen't support java11 yet and suspect that is the
> reason Nifi won't lunch.
> I am trying to get around this by using jenv.
> Having a look at the screenshot below you can see when I launch NiFi it
> believes the java home is still set to Java11.
> I suspected it's realted to this: [https://github.com/jenv/jenv/issues/224]
> in summary, I suspect NiFi is pointing to a full static path to the java file
> opposed to referencing $JAVA_HOME
> I'm hoping if this is the case, it can be improved to recognize the change
> better.
