獲取例外 - co.paralleluniverse.fibers.SuspendExecution在執行中CordaM13流

Question

你好琴絃隊，

我創建階乘Oracle服務和琴絃M13形成兩間的流動。

從控制檯執行流程時出現以下錯誤。

co.paralleluniverse.fibers.SuspendExecution：糟糕。忘記測試一種方法 用-Dco.paralleluniverse.fibers.verifyInstrumentation = true 運行你的程序來抓到罪魁禍首！

From logs, i found following warning message:

Answer 1

它看起來像你在你的流程的一個，或者您從流調用的方法之一缺少@Suspendable註解。

可能最好是自由地添加註釋以查看它是否刪除錯誤，然後逐漸減少以查看哪個是違規方法。
