【已结算】ClassLoader.loadClass加载Narhon引擎时报错Nest-host class_info_index 21 has bad constant type【赏金10元】
运行时报错：Caused by: java.lang.ClassFormatError: Nest-host class_info_index 21 has bad constant type in class file jdk/nashorn/internal/codegen/OptimisticTypesPersistence$5
jvm使用的是jdk11，公司针对openjdk11做过修改，但是看这部分源码与openjdk11是一致的。
没有解决思路，所以还没有尝试任务解决方法。
运行代码是：
// 执行表达式
log.info("计算公式控件----执行的表达式为：{}", formula);
//替换中英文括号
formula = formula.replace("（", "(");
formula = formula.replace("）", ")");
Object result;
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("JavaScript");
try {
result = engine.eval(formula);//
} catch (ScriptException e) {
return "0";
}
if (Objects.isNull(result) || !NumberUtils.isParsable(String.valueOf(result))) {
return "0";
}
return String.valueOf(result);
}
报错代码是：engine.eval(formula);
报错栈是：
