在CordaM13中执行流时获取异常-co.paralleluniverse.fibers.SuspendExecution

你好，科达队

我已经创建了阶乘oracle服务，并在Corda M13中创建了两方流

我在从控制台执行流时遇到以下错误

co.paralleluniverse.fibers.SuspendExecution:Oops。忘了给一种方法加仪器 使用-Dco.paralleluniverse.fibers.verifyInstrumentation=true运行程序 抓住罪犯

From logs, i found following warning message:

看起来您在某个流或从流中调用的某个方法上缺少了

注释

最好是随意添加注释，看看它是否消除了错误，然后逐渐减少，看看哪种方法是有问题的方法
