Hi,
I'm trying to execute the test cases locally in my current Oxygen IDE, for example theĀ org.eclipse.ui.tests.api.IWorkbenchPageTest. But I get exceptions on starting the tests and I'm not able to solve them.
java.lang.ExceptionInInitializerError

The same applies if I try to start a test suite, Even when I try to use one of the available launch configurations.
Am I missing something here? Our wiki page does not show any hints on that.
