Bug 173902 remove EXPERIMENTAL markings from 3.3 IDE Undo API
Need to remove the EXPERIMENTAL javadoc from the new API I introduced in 3.3. See org.eclipse.ui.ide.undo org.eclipse.jface.fieldassist
bundles/org.eclipse.ui.ide/src/org/eclipse/ui/ide/undo/CopyResourcesOperation.java
return getErrorStatus(UndoMessages.CopyResourcesOperation_NotAllowedDueToDataLoss);
			}
		}
		
		if (status.isOK()) {
			status = computeDeleteStatus();
		}
		
		
		if (status.isOK() && resourceDescriptions != null
				&& resourceDescriptions.length > 0) {
			status = computeCreateStatus(true);
		}
		return status;
	}
	/*
	 * Record the original resources, including a resource description to
	 * describe it. This is so we can make sure the original resources and their
	 * subtrees are intact before allowing a copy to be undone.
	 */
	private void setOriginalResources(IResource[] originals) {
		originalResources = originals;
		snapshotResourceDescriptions = new ResourceDescription[originals.length];
		for (int i = 0; i < originals.length; i++) {
			snapshotResourceDescriptions[i] = ResourceDescription
					.fromResource(originals[i]);
		}
	}
}
