mysql - 更新到 mysql-connector-java-5.1.44 后，MySQL JDBC 数据源查找失败

Question

考虑以下代码片段：

try
{//try to connect
    conn = DatasourceProvider.getDatasource("java:comp/env/jdbc/mysql/my_db").getConnection();
}
catch(Exception ex)
{//failed to acquire connection from the pool, retry
    ex.printStackTrace();
}

当我mysql-connector-java-5.1.10-bin.jar在 tomcat 8.5 中加载运行它时，它可以正常工作，但是当我更新到mysql-connector-java-5.1.44-bin.jar它时会引发以下异常：

javax.naming.NameNotFoundException: Name [jdbc/mysql/my_db] is not bound in this Context. Unable to find [jdbc].
    at org.apache.naming.NamingContext.lookup(NamingContext.java:816)
    at org.apache.naming.NamingContext.lookup(NamingContext.java:159)
    at org.apache.naming.NamingContext.lookup(NamingContext.java:827)
    at org.apache.naming.NamingContext.lookup(NamingContext.java:159)

    at org.apache.naming.SelectorContext.lookup(SelectorContext.java:163)
    at javax.naming.InitialContext.lookup(InitialContext.java:417)

这发生在 MySQL5.6 和 MySQL5.7 上。
任何想法？
