I'm getting the following after running Java: Clean Java Language Server Workspace as @DotIN13 proposed:
[Error - 11:07:30 PM] Connection to server got closed. Server will not be restarted.

For me the code decorations (probably those microsoft/vscode-java-test#470) for running tests vanish. I'm not sure if this is related.

[zs19940317]

the same error as above, is there a solution?
