Description Debbie Wilson CLA 2001-10-10 22:49:03 EDT 
I have a group of tests which require the platform to be started before each test.  For
	example:

	String[] testNames = { "test1", "test2", {test3");

	for (int i = 0; i < testNames.length; i++) {
		...
		new Main().run (<argument list including "-application " + testNames[i]>);
	}

	This fails when trying to start up the second run (for test2) with the following:
java.lang.Error: factory already defined

The solution is to launch each invocation of the platform in a separate VM.  I 
have created a simple framework for doing this.  See the new classes 
SessionTestLauncher, WorkspaceSessionTest, and RunNewSessionTests in the 
ZZDJTest project.  See me for more details...
