java - NetSuite java.lang.NoClassDefFoundError : sun/io/MalformedInputException on getConnection

Question

尝试使用 DriverManager 在 java 中连接时出现以下错误。我查遍了整个网络并没有找到解决方案。有人可以告诉我以下错误的原因或解释如何解决它。

conn = DriverManager.getConnection(connectionString, login, password);

该 NetSuite 库使用的异常不是 Java API 的一部分，但曾经是 Sun/Oracle Java 实现中内部类的一部分。由于该类不是 API 的一部分，Oracle(以及在此之前的 Sun)可以随意删除它；他们做到了。它不包含在 Java 8 Update 25 中；不知道什么时候被删除了。

这就是为什么不应在应用程序中使用 Java 附带的 sun.*、com.sun.* 和 com.oracle.* 包中的类的原因之一，因为它们可能会发生更改，并且可能随时被删除。

您应该询问 NetSuite，他们是否有不使用此类的较新驱动程序。
