The document discusses ways to improve Java applications using Oracle's GraalVM, including using GraalVM's native image tool to compile applications into native executables, using native build tools to compile applications ahead-of-time, and deploying statically-linked applications in lightweight container images. It then outlines a demo that shows building a native executable from a Spring Boot application using GraalVM, adding the executable to a container image, and automating the build process with GitHub Actions.
