SonarLint Eclipse error during startup: hotspots

  • Operating system: Windows 10
  • Eclipse: 2022-12
  • SonarLint plugin version:
  • Programming language you’re coding in: Java/JS
  • Is connected mode used: Connected to SonarCloud

During every startup of Eclipse, the SonarLint console contains the error about the security hotspot handler.
Here is an extra of the log:

Starting SonarLint for Eclipse
Unable to start security hotspot handler
Starting SonarLint engine for connection 'SonarCloud/<hidden for privacy>'...

Should we worry about this?


Thanks for reporting the issue. This message means that we were not able to start our local HTTP server that is used for the open hotspot in your IDE feature and a few other SonarLint <-> SonarQube communication.
This is not a blocker for the daily use of SonarLint, but it would be great to understand the root cause, since we plan to rely more and more on this local server.

Can you please enable verbose logs and restart Eclipse, to have more details in the SonarLint console?

Hello @Julien_HENRY!
Today I cannot reproduce the issue.
So my wild guess is that it might have been caused by some process occupying the 64120 port.
Since now I see successful start of the security hotspot handler:

Started security hotspot handler on port 64120

So most likely - not in an issue at all. In case it’s reproduced I’ll provide the logs.
