Do you mind downloading the distro from https://spring.io/tools and trying it out? Curious to see if you'd get the same error with it...

Now, what are the contents of C:\Users\ljanaswa\Applications\eclipse on your machine? Do you see any application.yml or application.properties files in there?

[BoykoAlex]

Do you mind trying the following:

1. Locate the spring-boot-language-server-1.57.0-SNAPSHOT-exec.jar under /Eclipse/plugins/org.springframework.tooling.boot.ls_1.57.0.202409101848/servers
2. Try executing java -jar <the jar> from that folder. Does it start or crashes?
3. If starts up fine try java -jar <path to the same jar> from the folder C:\Users\ljanaswa\Applications\eclipse on your machine

[jlmanohar]

Now, what are the contents of C:\Users\ljanaswa\Applications\eclipse on your machine? Do you see any application.yml or application.properties files in there?

This is just where I unzipped the enterprise java version of eclipse 2024-09

[BoykoAlex]

Okay, you didn't put anything extra in there, right? Just checking for a possible cause...
I was unable to reproduce it so far... Everything worked fine on mac. I've tried Win 10 machine but wasn't able to install sts via update site... some proxy issue I suppose, not sure... but the issue doen't seem to be platform related to me...
Please try launching the JAR as described above if you can :-)

[jlmanohar]

Sure, let me retry and get back.

I doubt I may have a corrupted install for some reason, though the other features of sts4 like dashboard works just fine.
If launching standalone doesn't work, I will try out a fresh install in some different folder too and get back.

[jlmanohar]

Okay, you didn't put anything extra in there, right? Just checking for a possible cause...

And no, the root folder has no modifications, eclipse ini... And all other files are stock, though I have sonarqube and jboss tools as extra plugins from marketplace, not sure if it will impact it though as their features work just fine

[jlmanohar]

I dont have java 21 installed, so i used the same jre that comes pre installed with eclipse and its the same error. The hash of the jar is as follows
SHA1: 61233b94b1b26a958817ae5ff374341228d39981

[jlmanohar]

Does it depend on something from the windows os ? i am on this version of windows on the system having issues

[jlmanohar]

Hmm, seems weird, i copied the exact installation as zip in my personal laptop and it seems to be working. So looks like compatability issue with older versions of windows. Are you aware of such requirement ?

I don't know if there is a compatibility issue but I wouldn't be surprised if there is... I have an old Windows 10 machine version 22H2 (installed in 2020) and was able to test this on it today - worked just fine. Version 1803 seems rather old. It is the new JAR layout that we are using with the language server JAR executable and likely there is something missing or being old in the platform to work with it.
The NPE from the stack trace is language server id being null. This id comes from the application.properties file inside the language server JAR. For some reason spring doesn't pick up that properties file in the case of the old Win. Not sure why that is...
