Oracle is planning to release a Critical Patch Update for Java on April 18, 2017. Customers running Demantra versions 12.2.3 and earlier must take action to obtain new JAR files that have been signed using the SHA-256 algorithm in order to prevent users from not being able to access the Demantra application after the April Critical Patch Update for Java is applied. Be aware that this update will render Demantra versions 12.2.3 and earlier inaccessible unless these actions are followed.
The Security Warning will state that an unsigned application is requesting permission to run. Although the Security Warning gives the impression that if you choose “Run” the application will run, this is not the case. If you choose “Run” you will still encounter errors with the Java applet.
Demantra versions 12.2.4 and later use the SHA-256 algorithm and will not be affected by this Java update. Customers running Demantra 12.2.4 or later can ignore this note.
To determine your current Demantra version and build, sign-on to Demantra Collaborator Workbench and select “Help” and then “About”. This will display a pop-up window showing the version number and build.
