In the coverage report's compilation unit source view, executed lines are shaded in green whereas non-executed lines have no background shading. This is contrary to the (more useful) presentation used by the jacoco:report Ant task and the EclEmma source file rendering, where:

• executed lines have green shading
• partially executed lines have amber shading (JaCoCo plug-in uses green)
• non-executed lines have red shading (JaCoCo plug-in uses white)

In addition, the jacoco:report Ant task and EclEmma both provide a tool-tip summarizing branch coverage for lines which contain control flow constructs; the JaCoCo plug-in does not.
