mvel2报错：java.lang.VerifyError method: getKnownEgressType signature

环境信息：

jdk：8

mvel2：2.0.19

异常信息：

java.lang.VerifyError: (class: ASMAccessorImpl_3009129941634644382940, method: getKnownEgressType signature: ()Ljava/lang/Class;) Illegal type in constant pool

调用的方法是org.mvel2.MVEL类的以下方法：

public static Object executeExpression(Object compiledExpression, Object ctx, Map vars)  

完整信息：

ASMAccessorOptimizer的部分源码：

可以看出mvel2的这个版本不支持jdk7和jdk8，升级下版本就好了
