问题描述：

有人报告 SAXBuilder 存在bug：打开文件后并不释放文件资源，结果多次打开同一个文件后，会导致”too many open files“错误。

解决：

将下面的做法

SAXBuilder builder = new SAXBuilder();File xmlFile = new File(path);Document document = (Document) builder.build(xmlFile);

改成这样

InputStream xmlFile = null;try {SAXBuilder builder = new SAXBuilder();xmlFile = new FileInputStream(your_file_path);Document document = (Document) builder.build(xmlFile);} catch (...) {...} finally {try {xmlFile.close();} catch (IOException e) {...}}

即，在finally 代码块中，强制释放文件资源。
