   The JaCoCo build renames all classes contained in the

   <code>jacocoagent.jar</code> into classes with a 

-  <code>org.jacoco._&lt;hexid&gt;</code> prefix, including the required ASM

-  library classes. The identifier is created during the build from a hash sum,

-  but could also be a random identifier. As the agent does not provide any API,

-  no one should be affected by this renaming. This Trick also allows that

-  JaCoCo tests can be verified with JaCoCo itself.
