DataProvider test appear under category "Unrooted test" in JUnit Eclipse plugin #7

Using Eclipse JUnit plugin some test cases appear under the category "Unrooted tests" instead of the expected class name, see Unrooted Tests Eclipse JUnit

See the reproducer in com.tngtech.test.java.junit.dataprovider.DataProviderEclipseJUnitPluginUnrootedReproducerAcceptanceTest for more information.

Findings so far:

searching the web for "unrooted junit test" resulted only in some problems using junit-3 with junt-4-runner :(
Problem occurs if your test data references an object having no toString() method and therefore using Object.toString()
Problem occurs if you return Integer.toHexString(super.hashCode()); as toString() method, whereby hashCode() must use Object.hashCode() (using Eclipse generated hashCode() function works normally)

For a @Parameterized test using an equal "data provider" it is working because the JUnit Eclipse plugin just shows indices to distingish between the different test data such that the test will not be show as unrooted. This would also work for DataProviderRunnerbut it not really what I desired ...

Having a more precise look in a silent minute made clear that I missed the forest for the trees ... As the above screenshot shows the data simply changed because com.tngtech.java.junit.dataprovider.DataProviderRunner.computeTestMethods() was called multiple times :(
