The OpenJDK Quality Group is promoting the testing of FOSS projects with OpenJDK builds as a way to improve the overall quality of the release.
Including additional properties files in the main security properties file allows for better management of security properties across multiple JDK releases.
The inclusion mechanism ensures robust security and prevents misconfigurations by listing files explicitly and throwing a fatal error for missing or inaccessible files.
Including other properties files offers benefits such as override priority, automatic propagation of updates, and consistent security policies.
