Jacoco (and life in general) doesn't like having different classes with same full name.
Here are the culprits in that case:

mistria at mistria--rh:~/git/jbosstools-webservices$ find . -name Logger\$1.class
./plugins/org.jboss.tools.ws.jaxrs.ui/target/classes/org/jboss/tools/ws/jaxrs/ui/internal/utils/Logger$1.class
[...]
./tests/org.jboss.tools.ws.jaxrs.ui.test/target/classes/org/jboss/tools/ws/jaxrs/ui/internal/utils/Logger$1.class
{quote}

You should consider either having the test directly consuming the Logger from the non-test bundle, or at least change the package when duplicating a class.
