Topics of interest (not limited to):


9:00 AM - Welcome

9:15 AM - Keynote:  Tom Rodriguez (Oracle Labs)
          Title:    Graal as a native JIT in GraalVM
          Abstract: This talk will discuss the design and implementation of libgraal, the
                    Graal and Truffle JIT compiled into a static library using Native Image
                    that is used as the default JIT in GraalVM. It will describe the
                    challenges of interfacing libgraal with HotSpot, the way native
                    compilation mode differs from the pure Java compilation mode and the
                    various ways Substrate technologies are used within the library itself.
          Bio:      Tom Rodriguez started worked on the JDK around 1.1 and worked on HotSpot
                    starting in 1.4, primarily on the client and server compilers.  For the
                    last six years he's been a member of the Graal compiler team and was the
                    primary implementor of libgraal.
