Issue about JUnit4 when running a RCP test with ANT

[jasonwang]

I tired several RCP app tests with ANT according to the WindowTester ContactMngrRCP sample. They work properly except the following issue:

If a test contains JUnit 4 annotations, such as @Test, I got the error: [java.lang.Exception: Could not find plugin "my_test"] in the html report.

I know JUnit 4 is not fully supported by WindowTester so far, but is there a way to specify Junit 3 in the command line and keep these JUnit 4 annotations in source files?
