I could not reproduce the issue on latest version of sonarjava.
This should not happen thanks to the fix provided in https://jira.sonarsource.com/browse/SONARJAVA-2204 which should be part of SONARJAVA since version 4.8.

If the problem persists, can you please try to upgrade to latest version of SonarJava and provides log of analysis ? Thanks.
