+ Depending on source formatting a single line of a source code may refer to
+ multiple methods or multiple classes. Therefore the line count of methods
+ cannot be simply added to obtain the total number for the containing class.
+ The same holds true for the lines of multiple classes within a single source
+ file. JaCoCo calculates line coverage for classes and source file based on the
+ actual source lines covered.
