I would like to consult you in reference to the checkstyle Plugin for Jenkins.
We currently use the plugin in our organization, we use version 3.35, on a Jenkins version 1.480.

The point is that we have detected that the data displayed in the report showing Jenkins, do not correspond exactly to the data in the file generated by Checkstyle(checkstyle-result.xml).
We have counted the number of error tags '<error>' and sometimes there are more than the shown by Jenkins checkstyle plugin.

Is there any known problem?

I hope you have understood me.
Thank you for your time and effort.
