Canonical's OpenJDK builds promise Java devs more speed - and a whopping 12 years of security support


The company is also aligning Ubuntu's and OpenJDK's release cadences.

They are built using an open-source tool called Chisel, which extracts only the required "slices" (portions) of Ubuntu packages, ensuring that only the runtime and its direct dependencies are included. Moreover, of those security holes, the vast majority (63%) of high- and critical vulnerabilities arise from indirect dependencies -- third-party libraries that are included, often unknowingly, in application builds. Besides security, Canonical is addressing Java's traditional challenge of slow startup times by packaging and supporting both GraalVM and Coordinated Restore at Checkpoint (CRaC).
