推荐答案

Java 7 引入了更严格的验证，并稍微改变了类格式——包含用于验证代码是否正确的堆栈映射.您看到的异常意味着某些方法没有有效的堆栈映射.

Java 7 introduced stricter verification and changed the class format a bit—to contain a stack map used to verify that code is correct. The exception you see means that some method doesn't have a valid stack map.

Java 版本或字节码检测都可能是罪魁祸首.通常这意味着应用程序使用的库会生成未通过更严格验证的无效字节码.因此，开发人员只能将其作为错误报告给库.

Java version or bytecode instrumentation could both be to blame. Usually this means that a library used by the application generates invalid bytecode that doesn't pass the stricter verification. So nothing else than reporting it as a bug to the library can be done by the developer.

作为一种解决方法，您可以将 -noverify 添加到 JVM 参数以禁用验证.在 Java 7 中，还可以使用 -XX:-UseSplitVerifier 来使用不太严格的验证方法，但在 Java 8 中删除了该选项.

As a workaround you can add -noverify to the JVM arguments in order to disable verification. In Java 7 it was also possible to use -XX:-UseSplitVerifier to use the less strict verification method, but that option was removed in Java 8.
