When JUnit and TestNG tests are in same project, only one set gets run

The attached Maven project has two tests: one JUnit test and one TestNG test. According to the documentation, in this case TestNG should run both tests.

Run "mvn test". Only the TestNG test will run. If you modify the pom to set the property "junit=true", only the JUnit test will run.
