Just wanted to close the loop before contacting SonarQube.
The issue appears not to be in Jacoco but instead in SonarQube. In the
failed scenario and the workaround scenario we discovered the appended
jacoco.exec is exactly the same.

Details
Even if a child pom uses a different groupId from its parent if the
artifactid name is the same the code coverage will disappear for all child
modules.
In app/pom.xml Changing
<parent>
<groupId>org.free2create.jacoco.mvp.reports</groupId>
<artifactId>app-reports</artifactId>
<version>7776.0.0.0-SNAPSHOT</version>
<relativePath>../</relativePath>
</parent>
<groupId>org.free2create.jacoco.mvp.app</groupId>
<artifactId>*app-reports*</artifactId>
To
<parent>
<groupId>org.free2create.jacoco.mvp.reports</groupId>
<artifactId>app-reports</artifactId>
<version>7776.0.0.0-SNAPSHOT</version>
<relativePath>../</relativePath>
</parent>
<groupId>org.free2create.jacoco.mvp.app</groupId>
<artifactId>*app-reports-app*</artifactId>
Works around the issue for the created demo code and in our real
application.
