Oracle JDBC getGeneratedKeys内存泄漏

Question

我正在使用JDBC Statement.RETURN_GENERATED_KEYS（https://docs.oracle.com/cd/B19306_01/java.102/b14355/jdbcvers.htm#CHDDJABH）来获取生成的ID和带有序列的插入时间，例如： 插入MY_TABLE（ID，TEXT）值（MY_SEQUENCE.NEXTVAL，'mytext'）;

然后我正在运行以下代码：

String query = "INSERT INTO MY_TABLE(ID, TEXT) VALUES(MY_SEQUENCE.NEXTVAL, 'mytext')";
try (
                PreparedStatement statement = connection.prepareStatement(query, new String[]{"ID"}) {
            statement.executeUpdate();

            try (
                    ResultSet result = statement.getGeneratedKeys();
                    ) {
                if (result.next()) {
                    System.out.println(result.getInt(1));
                }
            }
        }

它按预期工作，但是当我停止Tomcat时，出现以下错误：

The web application [SID] created a ThreadLocal with key of type [oracle.jdbc.driver.AutoKeyInfo$1]........but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.

在getGeneratedKeys（）调用之后，我没有找到任何有关处理资源的文档！

有人可以帮助我吗？

谢谢！
