A rewrite with performance as the primary motivation is likely to be faster in general, but yes: avoiding garbage collection pauses is a substantial advantage for a video game.

Howdy, I’m the Group engineering manager for Java at Microsoft (yep we now do Java!). Our group is working on minecraft’s perf (starting with server) so expect a steady rate of improvement over the 2021

  That's good to know, as server performance has been miserable since 1.13. Also good to hear that Java edition won't be slowly faded out :)

  This is actually really exciting to know :)

  The Java client is still in development?
  - pityJuke 6y ago
    Yes, Java is still important. The vast majority of user-generated content on servers is pretty much Java only. I also believe Java is still the authoritative version of the game (i.e. things come to Java first, before eventually coming out to Bedrock) - the lead game designer for Minecraft is a Java dev.

      I just really miss code connection in the Java version. It was the only way I found to teach programming for my kids, but they loath the C# version

  That's really good news. Thanks for still supporting the moddable java edition!
- karianna 6y ago
  To be clear to everyone. Not commenting or promising on the future product direction of the Java server or Java edition (my group doesn't own the product or product direction in any way shape or form). There's just some stuff we can look at now to improve the status quo since a bunch of my team are also fans of the game :-)

  Is there any chance of an official modding API to either Java or Bedrock? I know this is not the place to make such promises or announcements, but I’d be remiss not to ask.
  - Kuinox 6y ago
    IIRC there is one for the bedrock edition.
    - willis936 6y ago
      There is not. There is a scripting API that is very limited.

  Wow thats great! could you also recode tnt physics similar to how they were in version 1.7.10 so that tnt cannons can work again?
- hbrombeer 6y ago
  is there a way to get you up with Information or a talk about issues within the java server?
  - tntguy 6y ago
    yes you can add me on discord Lugburz#5061

lack of value types is also a sticking point, which the early code worked around but evolved to do less and less so. imagine arrays of references to 3d vectors each of which is an object on the heap, instead of inline, etc
- The_rationalist 6y ago
  Value types are coming soon: https://openjdk.java.net/jeps/390 https://openjdk.java.net/jeps/390 Probably supported as of Java 17
  - jdmichal 6y ago
    I've been hearing about value types in Java Coming Soon(tm) for like what, 5 years now? I'll believe it when I finally see it.
    - pjmlp 6y ago
      It took C++ 10 years to get concepts and modules into the standard, and experience shows 5 more until all bugs are sorted out. Probably 10 more for static reflection, executors and networking. Good engineering takes time.
      - jdmichal 6y ago
        Sure, but then stop advertising the damn thing. That's what I'm reacting to, the advertising. I'm fine with it taking as long as it needs to take. But I've been hearing about it for so long that all excitement for it is completely gone. When it actually drops, it will be met with the word "finally" instead of "awesome".
        The_rationalist 6y ago
        The JEP 390 that I linked should make you update your beliefs. Contrary to years ago, the value type implementation has matured so much that in a few months every Java program will have to be forward compatible with value types (otherwise they'll get warnings) We are long past the state of just talking about it, now it's being quickly incrementally added
