-----------------------------------
[~joewitt]
I created an AWS EC2 instance of REHL 7.5, installed openjdk 10.0.1, and copied
NiFi built from master (as it was on 6/4/2018) using Java 1.8.0_162.
On the EC2 instance, starting NiFi with openjdk 10.0.1 was successful.
As in the test I ran on docker with the openjdk:10 image, on the RHEL 7.5 AWS
EC2 instance, the --add-modules=java.xml.bind was added to the command that
starts NiFi:

> Project: Apache NiFi
> Issue Type: Sub-task
> Reporter: Jeff Storck
> Assignee: Jeff Storck
> Priority: Major
> Fix For: 1.7.0
>
>
> The following issues have been encountered while attempting to run a Java
> 1.8-built NiFi on Java 9:
> ||Issue||Solution||Status||
> |JAXB classes cannot be found on the classpath|Add
> "--add-modules=java.xml.bind" to the commant that starts NiFi|Done|
> |NiFI boostrap not able to determine PID, restarts nifi after nifi.sh
> stop|Detect if NiFi is running on Java 9, and reflectively invoke
> Process.pid(), which was newly added to the Process API in Java 9|Done|
>

>
> ||Unaddressed issues/warnings with NiFi compiled on Java 1.8 running on Java
> 9+||Description||Solution||
> |WARNING: An illegal reflective access operation has occurred
> ..._specific class usage snipped_...
> WARNING: Use --illegal-access=warn to enable warnings of further illegal
> reflective access operations
> WARNING: All illegal access operations will be denied in a future
> release|Reflective invocations are common in the code used in NiFi and its
> dependencies in Java 1.8|Full compliant migration to Java 9 and use
> dependencies that are Java 9 compliant|
