They are different PRs that are not related but have the same ci-test failure cause.

@sleshchenko can you confirm that this issue is still a blocker taking into account that it is open for more than a month?

[sleshchenko]

@garagatyi I agree that it is not blocker if it is not solved for more than a month. So, I changed severity to P1 since it makes ci-tests job unstable.
@dmytro-ndp Are there any plans to investigate this issue?

[dmytro-ndp]

@sleshchenko: actually the problem hasn't occurred on CI since then, and logging of workspaces has been fixed, AFAIK.
So, it's not quite clear how to reproduce the issue.

[sleshchenko]

@dmytro-ndp Then WDYT about closing this issue until we will not face this again?

[dmytro-ndp]

There is an issue about splitting JSON-RPC messages is still in progress, so problem could reproduce again if java language server will start producing abnormal error messages again.

This issue is related to #11961.
