SonarJava 6.1 upgrade results in a massive performance drop, coverage data gone

Hi @sergek,
Could you try to check your maven configuration and command line using this guide: [Coverage & Test Data] Importing JaCoCo coverage report in XML format?
Then could you check the content of target/site/jacoco-aggregate/jacoco.xml to figure out if the xml file does not contain coverage information or if JaCoCo XML report importer is not able to import the coverage report.
