Crashing on OpenJDK 25.0.2

[pettermoe95]

I get some different errors while using the LSP in both vscode and nvim. I'm not sure what to make of it. I am running a project with multiple modules, each containing their own build.gradle.kts. Any help is appreciated as I really want to be able to write kotlin code using my nvim setup. Let me know if you want some more information.

Thanks for reporting this!

Are you using this JDK to run the language server of as a JDK dependency for your project?
Have you tried any other JDK? (The language server and the VS Code extension come with a bundled JDK which is the preferred way to run them).

It would be very helpful if you could share a minimal sample project that reproduces the issue.

Note that #140 also mentions a similar error with "from RAW_FIR to ANNOTATION_ARGUMENTS" in it

We are using JDK 25 as a dependency for our project. It might be that it is completely unrelated to JDK25, but the error started showing up after we upgraded to 25. Now I have tried to revert back to 21 and the LSP still logs the same errors, and crashes. It is similar to #140 as @fedochet commented, it is too big to post the whole log here.

I understand it's not easy to debug this with this little information. I will try to set up a sample project that reproduces the error and come back to you. Thanks.

@pettermoe95 would you consider sharing the log files with us using this form? 🙏

https://uploads.jetbrains.com/

It allows to safely share files with our support engineers, and seems to be the best option in this case

We would need the resulting Upload ID from you:

After the upload is completed successfully, please share the Upload ID in the related support case.

Thanks a lot for the logs @pettermoe95 , it definitely makes it easier to diagnose the error!

Two questions: do you happen to develop on Windows OS, and also do you by any chance use WSL subsystem?

Hi again. I am using MacOS Tahoe 26.2, so no WSL.

I tried to create a repo that replicates the problem, but was not able to... However, I managed to get some more info about the problem I think.

I tried to copy the problematic project to a new folder, then delete some modules and remove some of the code (It's a project at work, and I can't share the whole codebase). By doing so I kept the same project setup, but the LSP was working without any errors.

I tried to figure out if maybe there was one specific module I deleted that was problematic, but no luck. I cloned the whole repo into a new folder, and then the LSP was also working, so I thought it had to be something with the build files. I deleted all build outputs, gradle folders, and still no luck. The LSP was still crashing inside the original repo.

In the end I figured out that if I just renamed the folder for my project from my_project to my_project_old, it actually started working. Maybe the LSP has a cache somewhere that is connected to the folder name?

Good news is I got it working again by just renaming the folder, but maybe it still might be of interest for you to figure out what was wrong here.

Hope this was of any help. I think it's great that you are working on a kotlin lsp! :)

[fedochet]

@pettermoe95 could you please show the contents of your PATH variable?

I believe that you have something like ~/.dotnet/tools in there, is that right?

That is correct:

[andrewmellen-toast]

I've also seen this on one of our repos (same error). I tried @pettermoe95 's findings of re-cloning the repo at a new path, and that did indeed fix the problem for me as well. I however do not have dotnet stuff in my PATH, figured I would add that datapoint.

Let me know if I can provide any more info that would be helpful! I can submit the stacktrace from my neovim lsp logs, but it seems like it is exactly the same as the others provided so I am not sure that there's much else to investigate from there. But if that's not the case I'd be happy to send it along.

I echo @pettermoe95 's sentiment that I appreciate the work that is being done here immensely, I am very excited to be able to effectively write Kotlin in other editors :)

[weareflo]

I believe the error for me started happening after we upgraded the project JDK to 25. My lsp-server does run on the internal JDK of the server which I believe is 21?

[weareflo]

I actually had to give up using the server all together cause the errors out on every buffer in the project. Using Nvim.

[danielferrari]

I have a similar issue. The navigation between classes/hover is not working. Using JDK 17, I haven't changed the JRE path to run LSP.

I'm using the path to the JDK 17 though in the "Path of JDK for symbol resolution". Maybe this is causing the issue?

I found a workaround for eliminating the cache by leveraging lsof -p <pid of kotlin-lsp> from the offending project directory, then looking for a file that has a name similar to this pattern: ~/Library/Application Support/JetBrains/analyzer/workspaces/6964872299e5c983a370656b23c17861.mv.db

Once I removed that file and restarted the lsp server, everything started working.

This fixed my issue, thanks a lot!
