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
update = true;
				IResource resource = resources[i];
				factory.copy(resource, getDestinationPath(resource, i));
			}
		}
		return update;
	}
	/*
	 * (non-Javadoc)
	 * 
	 * This implementation computes the ability to delete the original copy and
	 * restore any overwritten resources.
	 * 
	 * @see org.eclipse.ui.ide.undo.AbstractWorkspaceOperation#computeUndoableStatus(org.eclipse.core.runtime.IProgressMonitor)
	 */
	public IStatus computeUndoableStatus(IProgressMonitor monitor) {
		IStatus status = super.computeUndoableStatus(monitor);
		if (!status.isOK()) {
			return status;
		}
		
		
		
		if (originalResources == null) {
			markInvalid();
			return getErrorStatus(UndoMessages.CopyResourcesOperation_NotAllowedDueToDataLoss);
		}
		for (int i = 0; i < snapshotResourceDescriptions.length; i++) {
			if (!snapshotResourceDescriptions[i].verifyExistence(true)) {
				markInvalid();
