Oracle JDBC Driver with Java 9 java.lang.NoClassDefFoundError: Could not initialize class oracle.jdbc.OracleDriver

Question

我正在尝试让 Java 应用程序与 Java 9+ 一起使用。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 中运行良好，并且 2. 当运行在 9 中时所有其他 .jars 都正确加载。有没有人有任何运气运行 Oracle jdbc Java 9+ 上的驱动程序？

Answer 1

因此，一旦我为 DriverManager 打开跟踪日志记录，问题就自行解决了。 Sybase 的旧 jconn 驱动程序与 Java 9/10 冲突并导致 DriverManager 出错。鉴于它现在是一个已弃用的驱动程序，这是有道理的。
