Steps:

1. create a new plugin JUnit launch configuration for the debug test suite org.eclipse.jdt.debug.tests.AutomatedSuite
2. set the EE for the config to be 1.4, which is bound to a 1.4 JRE - in my tests using Sun 1.4 update 20
3. press run - tests run fine
4. kill the tests and open the launch dialog to the plugins tab
5. change the "Launch with" setting to 'plugins selected below'. Do not change any of the plugins, press save + run

Expected:

the tests would launch

Happens:

I would expect the configuration to launch the same as it did before, since I have not changed anything except to say what to launch, which is the same in both cases.
