    Naturally depends on the use case, yet they work good enough to be in business for 20 years.

    Android 5 & 6 (only changed back into JIT/AOT due to long compile times),

    Unfortunely the best well known, Excelsior JET, is no longer in business, most likely due to GraalVM and OpenJ9 being available as free beer, while PTC, Aicas Codename One are safe in their domains.

    There is also RoboVM ( as free beer, however it actually started as a commercial product, and the acquisition from Xamarin kind of stagnated it (naturally).

  • Can't Reproduce a Bug?

    At Codename One, we were using App Engine when our daily billing suddenly skyrocketed from a few dollars to hundreds. The potential cost was so high it threatened to bankrupt us within a month. Despite our best efforts, including educated guesses and fixing everything we could, we were never able to pinpoint the specific bug. Instead, we had to solve the problem through brute force.

  • The Holy Grail of Java Performance

    We use ParparVM which we wrote. It compiles a subset of Java 8 (sort of) to native by translating the bytecode to C and passing that through XCode. The reason we took this path and not the path of "direct to native", is that it allows for future compatibility.
