問題描述：

有人報告 SAXBuilder 存在bug：開啟檔案後並不釋放檔案資源，結果多次開啟同一個檔案後，會導致”too many open files“錯誤。

解決：

將下面的做法

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

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) {
		...
	}
}
