I would be interested as well mark

Kamil Erhard, a student of mine, and myself have prepared a paper draft on a novel framework for invokedynamic dispatch that we call DynaMate. The framework is meant to aid language developers in using java.lang.invoke more easily by automatically taking care of common concerns like guarding and caching of method handles or adapting arguments between callers and callees. By March 28th, we plan to submit the draft to OOPSLA, at which point we will probably also make the publication available as a Technical Report, and will also open-source the implementation. Right now, I would like to use this email to reach out to experts in the community to get some feedback on this work, both in terms of what could be improved w.r.t. the paper and in terms of the DynaMate framework itself. So please let me know if you are interested in obtaining a copy of the draft to then provide us with feedback. In this case I would email you the PDF some time this week. Best wishes, Eric P.S. Here is the current abstract: Version 7 of the Java runtime includes a novel invokedynamic bytecode and API, which allow the implementers of programming languages targeting the Java Virtual Machine to customize the dispatch semantics at every invokedynamic call site. This mechanism is quite powerful and eases the implementation of dynamic languages, but is is also hard to handle, as it allows for many degrees of freedom and much room for error. While implementers of some dynamic languages have successfully switched to using invokedynamic, others are struggling with the steep learning curve. We present DYNAMATE, a novel framework allowing dynamic-language implementers to define dispatch patterns more easily. Implementations using DYNAMATE achieve reduced complexity, improved maintainability, and optimized performance. Moreover, future improvements to DYNAMATE can benefit all its clients. As we show, it is easy to modify the implementations of Groovy, JCop, JRuby, Jython to base their dynamic dispatch on DYNAMATE. A set of representative benchmarks shows that DYNAMATE-enabled dispatch code usually achieves equal or better performance compared to the code that those implementations shipped with originally. DYNAMATE is available as an open-source project. -- Eric Bodden, Ph.D., http://sse.ec-spride.de/ http://bodden.de/ Head of Secure Software Engineering Group at EC SPRIDE Tel: +49 6151 16-75422 Fax: +49 6151 16-72051 Room 3.2.14, Mornewegstr. 30, 64293 Darmstadt _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
