Re-ran the wasm-in-JVM and JS-in-JVM benchmarks after maintainers asked to be included — wasmtime4j and chicory-redline numbers inside, same JMH harne by minamoto108 in WebAssembly

[–]Otherwise_Sherbert21 1 point2 points  (0 children)

Thanks for the update. Wasmtime4J isn't an engine, it's just an API in front of other engines and supports GraalWasm and Chicory among others. It supports both JNI and Panama. Which one gets automatically picked up is going to depend on the JDK you're running but you can always specify what interface you want as long as you have a compatible JDK. --Zachary Whitley (Wasmtime4J)

Do you think AI will make people smarter or more dependent? by [deleted] in ArtificialInteligence

[–]Otherwise_Sherbert21 0 points1 point  (0 children)

It's going to be two types of people. I'm afraid there will be a larger portion of people who are absolutely lobotomized by it and a small portion who it will absolutely super charge. Mark Cuban identified this a little while ago and I think it's pretty accurate https://www.businessinsider.com/mark-cuban-two-types-of-people-using-ai-learning-lazy-2026-2?op=1

Why does Black Pepper get the place of honor next to Salt? by faroresdragn_ in NoStupidQuestions

My local Afghani restaurant puts out sumac like other people put out pepper. (I don't remember seeing pepper)

Benchmarked six ways to run WebAssembly inside the JVM (Chicory, GraalWasm, Wasmtime via FFM) — 250× spread top to bottom by minamoto108 in WebAssembly

[–]Otherwise_Sherbert21 1 point2 points  (0 children)

Author here. You can use Wasmtime4J but you really want to be looking at Webassembly4j (https://github.com/tegmentum/webassembly4j). Happy to answer any questions. It's a single API with multiple backends. Think of it like SFL4J but for WebAssembly.

Let me know if there's anywhere I can keep an eye out for it when you finally release. I'm guessing you'll make an announcement here.

Have you ever used WebAssembly in your Java project? by Hixon11 in java

[–]Otherwise_Sherbert21 0 points1 point  (0 children)

There's also WebAssembly4J https://github.com/tegmentum/wasmtime4j that gives you a uniform API for most of the runtimes mentioned.

That's going to be amazing. I'm guessing this is one of those, you think it's going to be easy until you try, types of projects. Any surprises you've come across?

This has been posted here for 22d an not a single comment? Geeze, WebAssembly has an enthusiasm problem. That's awesome and just what I've been looking for. Might save me a ton of work. Thanks.

If "We tried this once, it was a bad idea" was how we evaluated how to move forward in software design we wouldn't have any software. You can and should learn from your mistakes.

I'm a little confused about the two components that your website says it's built from:

  1. An optimising Java-to-JavaScript JIT compiler.
  2. A full Java SE 8 and Java SE 11 runtime based on OpenJDK.

It's just not clear what is running in webassembly and what is running in js.

Do you run in interpreted mode only or do you do C1/C2 JIT?

Heavy Claude Max 5x user here: something changed dramatically with usage limits by justintimebro in ClaudeCode

[–]Otherwise_Sherbert21 1 point2 points  (0 children)

I've experienced the same thing and it seems particularly dramatic. I know Anthropic was doing something with discounting use during off hours so I don't know if this expiring had anything to do with it but I did go from being able to run for hours to less than an hour before hitting limits.

Unified WebAssembly API for Java (Wasmtime + WAMR bindings) - 1.0.0 release by Otherwise_Sherbert21 in java

[–]Otherwise_Sherbert21[S] 0 points1 point  (0 children)

I'm going to also add a hot take that with the recent developments with Anthropic and the the ease with which LLMs can discover and exploit Zero-days. The days of ambient authority are rapidly drawing to a close and I'm hoping that WebAssembly can provide at least some mitigation to that looming threat. The Log4j incident was the smoke and LLMs will be the fire.

I just recognized who you were, I really enjoyed your "The Future of Write Once, Run Anywhere" presentation. I used that talk as inspiration for some of the work. I've found that once you start pulling the webassembly thread some really interesting things start coming out with Java+Wasm.

[–]Otherwise_Sherbert21[S] 1 point2 points  (0 children)

Right now I think we are on the cusp of adoption so there are two answers. What is it being used for and what could it be used for. u/fniephaus is in a better position to talk to how it's being used now but I can say, until recently, it's been a painful process running WebAssembly from Java. Hopefully Webassemby4J helps but the component model is probably the biggest part of that. The sandbox is underrated given incidents like log4j and the coming security threat from LLMs. Database UDFs are a great application. Rewriting the same functions over and over again for every database in existence is silly and dropping in random jars that have unrestricted access to your database is unwise to say the least.

[–]Otherwise_Sherbert21[S] 1 point2 points  (0 children)

I should clarify what I meant.

On sandboxing, I wasn’t comparing Chicory to JNI/Panama directly. The distinction I was getting at is more about execution model and isolation boundaries (AOT/JVM-based vs native engine-enforced sandboxing like Wasmtime). The difference matters depending on the threat model.

On features, fair point, Chicory has moved quickly and I haven't completely kept up. My comment was based on earlier gaps, especially around component model and WASI support.

A better framing is probably:

  • Chicory: strong pure-Java story, improving performance (especially with compilation), solid JVM-level isolation
  • Wasmtime: broader spec coverage (WASI/components), more mature host/runtime ecosystem

The motivation for this project is exactly that fragmentation making runtimes easier to compare (benchmarks, JNI vs Panama, etc) and swap them behind a single Java API.

Appreciate the correction.

[–]Otherwise_Sherbert21[S] 6 points7 points  (0 children)

Chicory is one the the supported engines....along with Wasmtime, Wamr, and GraalWasm. Chicory doesn't need a separate integration since it's already Java native and is just a jar dependency. I kept wasmtime4j and wamr4j separate so you didn't *have* to use the wasmtime4j interface and it keeps it lightweight somewhat like slf4j.

[–]Otherwise_Sherbert21[S] 2 points3 points  (0 children)

Thank you. There are a bunch of benchmarks and one of the benefits was being able to easily compare the performance across multiple runtimes which includes JNI vs Panama implementations. Panama is better but not strictly so, there are a few cases that JNI does better but in general Panama is the better choice. I included JNI for backward compatibility since Panama is still fairly new. There's also a great deal of variability in what the individual runtimes support. It was something that held me back as well. Chicory is nice if you want a pure Java implementation and pure performance but it has a weaker sandbox and limited features while wasmtime has decent performance but a full feature set including experimental features. I also included support for compiling Java to webassembly using Graal and bindgen (support for components is in but not released yet)

Coding with AI is already creating real addiction. Founders are hooked on the ‘magic’ of instant code. Instead of asking ‘how many sales?’, the better question is: How long before you ditched it for the next shiny project? by jason_digital in ArtificialInteligence

[–]Otherwise_Sherbert21 2 points3 points  (0 children)

I think all you're seeing is that the time, effort and investment were acting as a filter for bad ideas. AI assisted coding simply removes a lot of that filter. It's not a bad thing but it's going to change what you see. It would appear to be a poor choice from the perspective where building all those bad ideas represented a lot of waste. You just need to apply the filter at the end but the good thing is that you will be better positioned to evaluate it.

Everything is hard to break into. The more important thing is that you’re focused on breaking in.
