Issue/Introduction

The RA REST Agent fails to do REST calls to an secured endpoint. It was previously working using OpenJDK v11 but now fails. Switching to a different java such as Oracle Java as a workaround seem to work.

Cause

Checking the last date modified on the cacerts of the REST Agent and the REST Endpoint can be a good way to check if they are mismatched

Resolution

Update to the latest build of OpenJDK (including the SSL authentication to the REST endpoint) after making sure that the cacerts are exactly the same.
