Deprecate the JAR Index feature (JDK-8302819) by jorsol · Pull Request #268 · codehaus-plexus/plexus-archiver (original) (raw)

The JAR Index mechanism is a legacy optimization from early JDK releases to allow downloading of JAR files to be postponed when loading applets or other classes over the network. The feature has been disabled by default since Java 18. Time has come to remove the feature from the Java runtime and also to add a warning to the jar tool when the -i/--generate-index option is used.
