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/AbstractWorkspaceOperation.java
statusMessage = NLS
					.bind(
							UndoMessages.AbstractWorkspaceOperation_ErrorInvalidMessage,
							getLabel());
		}
		return new Status(IStatus.ERROR, IDEWorkbenchPlugin.IDE_WORKBENCH,
				OperationStatus.OPERATION_INVALID, statusMessage, null);
	}
	/**
	 * Return a warning status describing the warning state of an operation
	 * using the provided message and code.
	 * 
	 * @param message
	 *            the message to be used in the status, or <code>null</code>
	 *            if a generic message should be used
	 * @param code
	 *            the integer code to be assigned to the status
	 * @return the warning status
	 */
	protected IStatus getWarningStatus(String message, int code) {
		String statusMessage = message;
		if (statusMessage == null) {
			statusMessage = NLS
					.bind(
							UndoMessages.AbstractWorkspaceOperation_GenericWarningMessage,
							getLabel());
		}
		return new Status(IStatus.WARNING, IDEWorkbenchPlugin.IDE_WORKBENCH,
				code, statusMessage, null);
