Unable to suppress TODO diagnostics using java.errors.reportTodoComments or java.errors.suppressedDiagnostics

[meethey]

I'm encountering an issue where TODO comments in Java files are still being reported in the Problems window, even after explicitly disabling them via workspace settings.

Steps to Reproduce:

1. Create a new Java file with a TODO comment:

public class Test {
public static void main(String[] args) {
// TODO: This is a test
System.out.println("Hello");
}
}

2. Add the following to .vscode/settings.json:
   {
   "java.errors.reportTodoComments": false,
   "java.configuration.taskTags": [],
   "java.errors.suppressedDiagnostics": [
   "536871362"
   ]
   }

3. Restart VS Code and optionally run Java: Clean Java Language Server Workspace.

Expected Behavior:
The TODO comment should no longer appear in the Problems window.
Actual Behavior:
The TODO comment is still reported as an informational diagnostic:
TODO: This is a test Java(536871362)

No other extensions (e.g., SonarLint, CheckStyle) are active.
Verified that the issue persists even in a minimal workspace with extensions disabled.

"java.errors.reportTodoComments" and "java.errors.suppressedDiagnostics" don't exist. I have no idea where you get that from. As you can see from your screenshot, all those settings with a darker color mean they don't exist.

Anyways, you can suppress those TODO warnings by referencing an eclipse preferences file like this:

• create a .vscode/java.prefs file containing:

org.eclipse.jdt.core.compiler.problem.tasks=ignore

• in your .vscode/settings.json, add:

"java.settings.url": ".vscode/java.prefs"
