Thanks to Ümit Seren and Slava Pankov, we now have a Java port that compiles both for the native JVM and the browser (via GWT compiler).
Here are the updated test results with the inclusion of Java:
Java's JVM jumps in first position resulting the fastest among all. Java on the browser via GWT does a pretty well job too, rivaling its direct competitor (C# to JS).
Get this test from GitHub or see my previous blog post about it.
