For legacy reason we are running a pretty old eclipse version (Eclipse Oxygen.3A Version 4.7.3).
Now that we have updated to SonarLint 5.5.0.23614, we see a lot of NullPointerException coming from SonarLint. Those occur after each navigation (when we bring an other Java editor Tab as active tab, more or less)
In the Error log view the Stacktrace look like this:
java.lang.NullPointerException

If I am not mistaken, the error comes from this line:
We will now downgrade to 5.3.0.19940, where this was working well.
