Hello,
I am running automated tests, and every other day or so, I get this exception,
coming from my tearDown method:

com.google.eclipse.testing.core.util.BaseTestCase$1.tearDown (BaseTestCase.java:79)
com.google.eclipse.testing.core.util.TearDownTestCase.tearDo wn(TearDownTestCase.java:84)
In my test, before calling super.tearDown, I call:
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().closeAllEditors(false);
So you can imagine that I'm a bit surprised that _any_ text editor remains open.
Incidentally, the NPE is coming from this line:
Display display= getSite().getShell().getDisplay();
The things I don't know:
1. is getSite() returning null?
2. is getShell() returning null?
3. which editor is still open?
4. is closeAllEditors really not closing all editors? (Note: I just discovered
that closeAllEditors returns false if not all editors close, so that's a start.)
5. how do I super-force all editors to close?
