无限循环 - stackoverflow 异常 jira scriptrunner

Question

我的代码在第 125 行和第 133 行级别有一个无限循环。 更具体地说，这些是线

   ComponentAccessor.getIssueService().transition(mycurrentUser, myresult2)

和线

IssueService.TransitionValidationResult myresult = ComponentAccessor.getIssueService().validateTransition(mycurrentUser, issue.getId(), transitionToBeDoneInt, inputParameters);

下面是我的完整代码。任何人都知道是什么导致了这个无限循环？我已经多次查看我的代码，我真的不明白哪里出了问题。我正在使用 Jira 和 scriptrunner 作为后置函数，它应该添加新评论。这段代码中没有任何递归。它只是应该做一个过渡，就是这样，没有递归。这个错误太奇怪了，因为即使代码没有显示任何递归迹象，我也有一个无限循环。

我的代码很简单，只需要执行1次转换和写注释，我的代码不需要递归和循环。

}
    

这是我的错误日志中打印的内容的片段

我没有测试它，但在我看来，您正在再次使用相同的转换来转换问题，这将再次执行该后处理函数，这将再次使用相同的转换转换问题，这将执行您的后处理函数再次......等等等等。 这也应该发生在同一个线程中，因此会导致 StackOverflowError，即使您的脚本没有任何递归或其他无限循环。

我很确定那里不需要您使用转换问题来转换问题的代码。您的脚本是一个 Post Function，它作为转换的最后一步发生。

transientVars['actionId']

应该给你确切的转换 ID，因此你最终会再次使用相同的转换来转换问题。

如果你只是想添加评论，那么只需要留下关于添加评论的代码，并删除所有关于转换问题的其余部分。
