Unless you report a blocking issue, we'll proceed with the release next Wednesday 05/29/2026. If you need to have more time, please tell me.

@angelozerr Did you actually mean next Wednesday (which would be 06/03/2026)? 05/29/2026 is this Friday. I am hoping you meant next week so that we can schedule time to test this new release.

No problem, next Wednesday is OK?

No problem, next Wednesday is OK?

Yes, I think I that should be enough time for us to test it.

mrglavas May 27, 2026

I believe we specifically wanted to test #294 assuming that is in LSP4IJ 0.19.5. (cc @dessina-devasia)

dessina-devasia Jun 1, 2026

@mrglavas @angelozerr Issue #294 is not fixed with the latest nightly build 0.19.5-20260601-015015. Thanks!

dessina-devasia Jun 2, 2026

@angelozerr Please find the attached logs and video evidence demonstrating Issue #294

Hi @angelozerr,
I encountered an exception while applying the MicroProfile quick fix. Could you please take a look? I’ve attached the screenshot, video, and logs for your reference.

@dessina-devasia thanks so much for your feedback. I think I have a fix for that and I also noticed that we have now an error with RedponseErrorException when codeAction quickfix is cancelled (I noticed that by fixing yiur issue)

I will ping you when nighty will fix thise 2 issues.

@dessina-devasia could you retry the nighty build please.

Sure @angelozerr

dessina-devasia Jun 1, 2026

@angelozerr I've tested this reported issue with latest LSP4IJ nightly (0.19.5-20260601-015015) and the issue is not occurring now. Thanks!

SergejSalnikov Jun 1, 2026

Could we please call pre-release builds 0.19.4.99-..., so that when new version is release we don't have to manually update it?

Wanted to raise a similar note: org.eclipse.lsp4j package is shipped with IJ and with LSP4IJ plugin and the versions are different.
Could we just reuse the platform version?

@SergejSalnikov I would like to do that but it will require to bump LSP4IJ to 2025.2 if I remember. See my PR #1379

More in 0.19.5 I have upgraded LSP4J to 1.0.0 because I am supporting LSP inlineCompletion

@mrglavas @SergejSalnikov @dessina-devasia I will delay the release because I have noticed after starting IJ with a lot of projects and editor opened that we can have some blocked thread for few seconds and I sometimes I loose some lsp features like diagnostics.

I have a PR which improves that that I will merge it but we need really have time to test it and see if there is no regression and no lock.

I have also improved IJ Quarkus with cancellable ReadAction and use a new strategy to discover id project is a Quarkus project.

We can discuss about that if you wish.

My plan is to merge my PR and you test it.

I will also bump lsp4ij to 0.20.0 because there are a lot of changes

@dessina-devasia is this nighty build fixes your issue with Jakarta LS quickfixes? Please try to open several projects, open some files, close it and reopen IntelliJ. Do you see some freeze? Please try editing files, rename, etc, find references etc, do you see some freeze?

@SergejSalnikov is the nighty build fixes #1566 ? I use cancellable RedAction, so perhaps it could fixes your issue?

SergejSalnikov Jun 3, 2026

Now I run into the following problem: java.lang.IllegalStateException: Duplicate RPC method textDocument/inlineCompletion.
Addressing that problem and then will report about the other issue.

My main problem now is that you pull a different version of eclipse lsp4j library that comes with the platform.

SergejSalnikov Jun 3, 2026

Finally I was able to hack around. #1566 doesn't run into deadlock anymore, but now it sometimes throws the following exception:

Lsp4j from platform doesn provide InlinneCompletion api right?

First it is a great news that cancellable ReadAction is working. I did a simple fix at #1579 which avoid using ReadAction to get document from PsiFile. Please retry nighty build.

Hi @angelozerr ,

I tested the LSP4IJ nightly build (0.20.0-20260607-051424) released yesterday and encountered the following issues:

Hover support is not working in bootstrap.properties and server.env (Liberty Language Server).
Hover support is not working in server.xml (Liberty LemMinX).

I don't see any textDocument/hover request?

dessina-devasia Jun 9, 2026

You are right @angelozerr. Seems textDocument/hover request is not sending. Let me check further. Thanks!

dessina-devasia Jun 9, 2026

Seems issue is not with LSP4IJ. Thanks

angelozerr Jun 9, 2026
Maintainer Author

That's great, but could you explain me what is the problem? Hover capability?

dessina-devasia Jun 12, 2026

@angelozerr This turned out to be an IntelliJ setting issue rather than a Liberty Tools/LSP4IJ problem. Screen Reader Support was enabled in my IntelliJ setup, which prevented textDocument/hover requests from being sent. After disabling it and restarting the IDE, hover in server.xml started working as expected.
