sqldeveloper-java.nio.BufferUnderflowException

在windows 10上启动sqldeveloper，然后尝试连接到12c数据库后，我们收到以下java错误stacktrace

尝试sqldeveloper版本4.2或17.2时会出现此问题

有什么想法吗

您需要在sqldeveloper安装中升级Oracle JDBC驱动程序。找到ojdbc8.jar并将其替换为可从OTN下载的最新版本。然后重新启动JDev，问题就会消失。

我在SQL Developer 18中也遇到了同样的错误。我将Oracle驱动程序降级为Oracle 12.1（）提供的驱动程序。我现在可以很好地连接了。

只是一个问题-大约是12.2。或12.1。Oracle数据库的版本？我想我在某处看到，最新的jdbc是针对12.1的，但不确定，可能是由于这个问题。如果不是这样的话，那么它与Sql开发人员有关。再次尝试下载，检查下载内容的完整性，重新安装。如果所有其他操作都失败，请尝试较低版本。我在SQLDEV4.2中遇到了许多连接问题。在Windows 10上，它基本上归结为一个与Windows 10相关的问题。可能是当前版本可能有一些错误，请尝试下载以前的版本欢迎使用堆栈溢出！请拿着这本书，四处看看，仔细阅读，尤其是和您可能希望在中创建一个帐户，并在中询问您的问题
