I have the following setup which is giving me a message stating that \"Constructor Calls Overridable Method\". I know this is happening, but my question is how to fix it so
The source of the error you see is PMD (search there for "overr"), and when constructing your example again, this warning is not triggered by this version of PMD (4.2.6). Sonar just integrates PMD, Checkstyle and other tools, and provides an overview. So check which version of Sonar (and PMD) you are using.
You can look at that in Sonar: Sonar > Quality Profiles > Search for "overr"
should highlight the rule you are using.
In Sonar, you can check which version of PMD you are using. Go to Sonar > Configuration > Update Center
, and look there at the version of PMD you are using.
