Additional Info:
We're trying to verify functionality of the CodeReady Studio's LTS per the recent Log4j CVE (https://tools.jboss.org/blog/12.21.1.ga.html). Our application is using OpenJDK 1.8.0.222, so most of our development team is running CodeReady Studio 12.13.0.GA. I personally have an install of 12.21.0.GA with RH 
OpenJDK 11.0.13.8 and the Software/Update functionality works OK.

• This issue also occurs for another member of my team with a fresh install
• It shouldn't be a cacerts issue (re: 12.21.0.GA works with the same JDK)
• We don't have any special proxy configurations and are using the default Network Connections.
