Similar issue reported by one SonarLint user even if the stacktrace is not the same.
https://jira.sonarsource.com/browse/SLE-177

At startup, SonarLint will analyze files opened in editors and may call in multiple concurrent jobs some JDT API.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug.

If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
