@1322561244 Could you try to disable Gradle For Java and run View>Command Palette>Java: Clean Java Language Server Workspace?

[1322561244]

@snjeza I disabled the 'Maven for Java' extension and executed the command, but it had no effect. The following error was prompted:
"Failed to delete c:\Users\Lenovo\AppData\Roaming\Code\User\workspaceStorage\2c0f30e692eae5311b6b2d1ec0197bd0\redhat.java\jdt_ws: Error: EBUSY: resource busy or locked, unlink 'c:\Users\Lenovo\AppData\Roaming\Code\User\globalStorage\redhat.java\1.46.2025092608\config_win\org.eclipse.core.runtime.extraData.1'"
This issue only occurs with a specific project. When I switch to other Spring Boot projects, the problem does not appear. To resolve this, I had to uninstall VS Code, thoroughly clean up its residual files, and then re-download and run it to get back to normal operation.

Trying multiple settings and disabling multiple extensions, still stuck displaying 'Initialize Workspace -21%'. The following is the log situation：

@1322561244 your server crashed after 2 seconds.

Extension version: 1.44.2025072308

Could you try the latest pre-release version?

[1322561244]

I tried using the latest pre-release version and also older release versions, but the issue still persists. This problem occurs intermittently when developing a Spring Boot project with VS Code. Currently, I am unable to reproduce it reliably.

[snjeza]

@1322561244 Are you using Extension Pack For Java? If so, which version are you using?

Can you add the following properties

"java.trace.server": "messages",
"java.jdt.ls.vmargs": "-Dlog.level=ALL -Djdt.ls.debug=true -XX:+UseParallelGC -XX:GCTimeRatio=4 -XX:AdaptiveSizePolicyWeight=90 -Dsun.zip.disableMemoryMapping=true -Xmx8G -Xms1g -Xlog:disable",
"java.compile.nullAnalysis.mode": "disabled"

to settings.json and send you server log - View>Command Palette>Java: Open Java Language Server Log File

[1322561244]

@snjeza I am using Extension Pack for Java version 0.30.2025102108. I tried as you suggested, but the issue still persists. However, when I copied all the project files to another location without changing any settings or extensions, this copied project did not have the problem and could compile and run normally.
