About the conference
The 2008 JVM Language Summit is an open technical collaboration among language designers, compiler writers, tool builders, runtime engineers, and VM architects. The talks inform the audience, in detail, about the state of the art of language design and implementation on the JVM, and the present and future capabilities of the JVM itself.
