JVM Continuations

Lukas Stadler, JKU



Continuations for the Hotspot JVM — Lukas Stadler

Continuation support is part of the MLVM effort. They are a powerful concept that allows implementation of many advanced language features like coroutines, green threads, etc. This presentation covers the basic concepts of the lazy continuation mechanism and the details of the actual implementation in the JVM.


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.

For a list of publications that were results of this collaboration (topics include SSA form, linear scan register allocation, ABCE, object inlining, escape analysis, compiler graph visualization tools) see:
