2.5.0.M2 LSP and VSCode works partially

Tags: #<Tag:0x00007faee07f1980>

I upgraded from 2.4.0 to 2.5.0.M2.
It looks like the LSP does not work together with VSCode any more.
This is my workspace setting, vevedock-64 is my host:

{
    "openhab.host": "vevedock-64",
    "openhab.port": 8080,
    "openhab.lspPort": 5007,
    "openhab.lspEnabled": true,
    "openhab.restCompletions": false,
    "workbench.iconTheme": "openhab",
    "openhab.karafCommand": "ssh openhab@vevedock-64 -p 8101 -t 'log:tail'",
    "git.ignoreLegacyWarning": true,
    "terminal.integrated.shell.windows": "C:\\WINDOWS\\System32\\WindowsPowerShell\\v1.0\\powershell.exe"
}

openhab.restCompletions": false was neccesary in 2.4.0 due to havy cpu load in 2.4.0.
Is this a problem now?
