==Graal - A Bytecode Agnostic Compiler for the JVM==
;Speakers: [http://labs.oracle.com/people/mybio.php?c=1400 Thomas Würthinger] (presentation): thomas.wuerthinger (at) oracle.com
:[http://www.ssw.uni-linz.ac.at/General/Staff/LS/ Lukas Stadler] (workshop): stadler (at) ssw.jku.at
;Project: http://wikis.sun.com/display/MaxineVM/Graal
;Slides: [[Image:GraalJVMSummit2011.pdf]]

===Abstract===
Graal is a just-in-time compiler written in Java that works with both the HotSpot VM and the Maxine VM [http://wikis.sun.com/display/MaxineVM/Home]. It is based on a port of the HotSpot client compiler from C++ to Java, but it takes new approaches in some key areas, most notably the intermediate representation (IR): Graal's IR consists of an SSA-form, "sea-of-nodes" program dependence graph.

Java as the implementation language makes it much easier to let frameworks and applications interact with and extend the compiler.
We think that this is a key aspect of Graal. The presentation provides an overview of Graal and gives examples for possible compiler extensions. The workshop should lead to discussions about which additional features Graal could provide that would benefit language implementors.

==Graal - A Bytecode Agnostic Compiler for the JVM==
;Speaker: [http://labs.oracle.com/people/mybio.php?c=1400 Thomas Würthinger] (presentation)
:[http://www.ssw.uni-linz.ac.at/General/Staff/LS/ Lukas Stadler] (workshop)
;Project: http://wikis.sun.com/display/MaxineVM/Graal
;Slides: ...

===Abstract===
Graal is a just-in-time compiler written in Java that works with both the HotSpot VM and the Maxine VM [http://wikis.sun.com/display/MaxineVM/Home]. It is based on a port of the HotSpot client compiler from C++ to Java, but it takes new approaches in some key areas, most notably the intermediate representation (IR): Graal's IR consists of an SSA-form, "sea-of-nodes" program dependence graph.

Java as the implementation language makes it much easier to let frameworks and applications interact with and extend the compiler.
We think that this is a key aspect of Graal. The presentation provides an overview of Graal and gives examples for possible compiler extensions. The workshop should lead to discussions about which additional features Graal could provide that would benefit language implementors.

Thomas Wuerthinger (wuerthinger@ssw.jku.at) - Sun

; Slides: [[Image:file.pdf]]

== Abstract ==
The current hotswapping mechanism in the HotSpot VM only allows changing the bodies of methods at runtime. We are working on an approach that allows arbitrary changes. This talk is about our experiences implementing a prototype in HotSpot that supports adding and deleting of methods and fields as well as performing changes to the class hierarchy. What are the conditions for dynamic code evolution to have a clear semantics and what kind of changes should be forbidden? What are meaningful applications of dynamic code evolution for Java and their requirements? The talk will conclude with ideas for future work to make dynamic code evolution stable and performant.

== Background ==
This project is part of a long-term collaboration between the HotSpot compiler group at Sun Microsystems and the Institute of System Software at the Johannes Kepler University Linz.
