【未解决】java使用c3p0时出现named-config with name 'xxx' does not exist

配置文件无任何问题，目前在网上未找到解决方案。
Java工程使用jdk13会出现以下问题：

使用jdk1.8不会出现以上问题。刚开始学java先标记一下，以后再来解决。

代码：

@Test
public void ConnTest2() throws SQLException{
		ComboPooledDataSource cpds = new ComboPooledDataSource("myc3p0");
		Connection conn = cpds.getConnection();
		System.out.println(conn);
	}

xml配置文件：

	
		
		com.mysql.jdbc.Driver
		jdbc:mysql:///test
