GAE uses Java 1.6, but you've compiled the code with Java 1.7. You need to recompile with Java 1.6. As per the comments, you're using Eclipse; you can set the Java compiler level in Java > Compiler section of project's properties. 这篇关于java.lang.VerifyError：期望一个堆栈图框架的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！ 08-06 01:35
