Invalid thread access

[banane...@gmail.com]

This was just caught via AERI. I'm not aware what exact user action I did to trigger it, and there was no popup or other error message. Seems you need to syncExec() that code or so.

Sonarlint 3.2 on Oxygen.

Hi,

Thanks for the feedback. Looking at the code, I can see there is indeed a potential issue. I will fix it "blindly" since I have no idea how to reproduce.

Ticket: https://jira.sonarsource.com/browse/SLE-204

"Blind" fix: https://github.com/SonarSource/sonarlint-eclipse/pull/110
