Java Error when Executing CIS-CAT Pro Assessor v4: "An Illegal Reflective Access Operation has Occurred"
Product Name
CIS-CAT Pro Assessor®
Product Version
v4.1.0 +
Date
May 7, 2021
Problem
As soon as I execute the a CIS-CAT Pro Assessor-CLI Assessment, and before the assessment begins, we see a warning message about Java as follows or similar.
Solution
You can ignore this error message provided that the scan moves past that step. You can refer to This section of the Assessor Configuration Guide - Introduction
This are the listed requirements from the CIS-CAT Pro Assessor Configuration Guide.
Requires:
Compatible version of JRE present on host or accessed via network share
Any JRE version from 8 to 14 is supported
64-bit Java recommended for faster performance
Java versions 9+ will receive “WARNING: An illegal reflective access operation has occurred”. This can be ignored and will not halt the assessment.
OpenJDK (free and open-source) implementations are supported. We have found this website easy to navigate. The official source is OpenJDK.
We always advise reading through the full Configuration Guide and System Requirements before beginning to install and run any of the CIS-CAT SecureSuite® Products
