JAR files signed with the MD5 algorithm will be blocked. This change will result in the Demantra application being blocked for most customers running Demantra versions 12.2.3 and earlier.
Note: If the Java settings on the client are configured for automatic updates, then the Java April Critical Patch Update will be applied automatically. If this occurs without taking the actions listed below, then users will not be able to access Demantra versions 12.2.3 and earlier.
