Vscode-java: "trigger parameter hints" (shift+cmd+space) action doesn't work

[jnesspro]

1) System.out.println();
2) shift+cmd+space
3) no parameter hints appeared
same for a constructor parameters.
I tried on 2 mac os machines, on stable and on insiders versions. Other languages support this feature (tried with golang, typeScript)

Mac OS
VSCode 1.32.0-insider, 1.31
extension version: 0.40

Add "java.signatureHelp.enabled": true to your settings.json

Oh. I'm sorry. Hope, I not only one and this issue will help someone.
