openoffice文件转换失败 ,文件被锁住? 400 报错

public static boolean conventToPdf(String sorcePath, String desPath) throws ConnectException, OpenOfficeException { File inputFile = new File(sorcePath); File outputFile = new File(desPath); OpenOfficeConnection connection = new SocketOpenOfficeConnection( normalPort); try { connection.connect(); DocumentConverter converter = new OpenOfficeDocumentConverter( connection); converter.convert(inputFile, outputFile); } catch (ConnectException e) {

		throw new ConnectException();
	} catch (OpenOfficeException e) {
		
		throw new OpenOfficeException("不是标准的office办公文件");
	}finally{
		if (connection != null) {
			connection.disconnect();
		}
	}
	return true;
}</pre> 

上面是代码  finally块中释放了连接，但是如果文件转化失败，这个文件就被锁住了，无法执行删除，正常无异常情况测试可以执行删除。
