Question

我试图让Java应用程序使用Java 9+。当在1.9 jre中运行时，我得到以下堆栈跟踪：

我已经确认类路径是准确的，因为1.这在Java 8中正常运行，并且2.在9中运行时所有其他.jars都已正确加载。有没有人在Java 9+上运行Oracle jdbc驱动程序有什么好运？

Answer 1

因此，一旦我为DriverManager打开跟踪日志记录，问题最终就会显示出来。 Sybase的旧jconn驱动程序与Java 9/10发生冲突，并导致DriverManager出错。既然现在已经不推荐使用该驱动程序，那就很有意义了。

带有Java 9的Oracle JDBC驱动程序java.lang.NoClassDefFoundError：无法初始化类oracle.jdbc.OracleDriver
