JVM Feature Request: The ability to preserve a complete JVM state (in this case with loaded Clojure stuff) and quickly start from there.

Does anybody know if something like that is possible/already exists?

All 3 not perfect, but have a look :)


I have used http://criu.org/ on Ubuntu 14.04 to checkpoint and restore a Java process running a Clojure nREPL server. It took 480 ms to checkpoint a 128MB process and 213 ms to restore on a 2.4ghz E5645.


Not quite what you asked, but I found people recommending this.

The majority of commercial JVMs that tend to be ignored on HN, provide JIT cache between runs and AOT compilation.
