After upgrading the UVC Webconsole to 6.10.x, being hosted in a Tomcat in https mode (url https://xxxxxxxxxxxx), some users having Java 7 as JRE are unable to launch it with the error:
Erreur sur le fichier PubClient.jar entré non signé ( unsigned entry)
Outdated and incompatible version of Java in workstations ( Java 7).
Release : 6.10
Component : DOLLAR UNIVERSE
Subcomponent: Univiewer.Console (Webconsole or Webstart)
UVC 6.10.x is incompatible with Java 7 or Java 6 as explained in the Compatibility Matrix.
Upgrade Java on the workstations to a supported version ( Java 8 or Java 11) for UVC 6.10.x, we recommend to use the latest Java 8 update available to avoid security issues.
In this case, workstation's Java was updated from Java 7 to Java 8 update 121 which solved the issue to download the jars from the Tomcat in https mode.
