Type: Bug

Hi Team,

Laguage Support for Java by Red Hat fails when .m2/repository directory is included as referenced library for the Java project.

Expected: No error.
Actual: VS Code becomes unresponsive and eventually plugin fails with OutOfMemory error.

Thanks

What is the size of your .m2/repository ? Also, do you have access to Java : Open Language Server Log File (from the command palette) to post any errors you find there ? It does seem to work, though it just takes a really long time (~2.5min) to get a response. Using an unmanaged project :

(I disabled shared indexing to better measure the final size of the index, and it was around 1.7GB.)
.vscode/settings.json

{
    "java.sharedIndexes.enabled": "off",
    "java.project.referencedLibraries": [
        "~/.m2/repository/**/*.jar"
    ],
}
$ du -sh ~/.m2/repository/
2.6G	/home/rgrunber/.m2/repository/

[Trace - 11:43:52] Received response 'workspace/symbol - (26)' in 152818ms.

I did occasionally notice this error :

[Error - 10:49:50] Sep. 26, 2024, 10:49:50 a.m. An internal error occurred during: "Update classpath Job".
