Java SonarQube 5.1分析失败，StackOverflower错误

我最近升级到了最新的SonarQube 5.1，但现在，我的maven版本开始失败，我无法确定是哪个文件导致了错误。maven项目是一个多模块项目

• SonarQube版本5.1
• 使用“mvn sonar:sonar”执行maven目标（使用版本2.6，并正确分析一些项目）

maven构建完成时出现以下错误：

对错误原因的调试有什么想法吗？我已尝试使用-debug标志。

问题已解决

---

我最终设置了一个本地实例，并使用调试器运行maven插件，这使我能够在异常处设置断点。我发现我们有一个测试用例（文件），它有一个由数百个字符串定义的字段。这个文件已经很长时间没有被编辑了，所以我猜整个堆栈大小已经从4.x更改为5.x。这个测试很难看，因此我的解决方案是重构它。我想另一个解决方案是增加java堆栈大小，但我没有尝试过。

奇怪的是project flex parentpom上的

：null

？知道null代表什么吗？版本、名称？准确地说，sonar 4.XT没有问题：堆栈没有改变，比如说：在版本5.x中，您使用最新版本的java插件进行语义分析，您很可能遇到了这个讨厌的错误：
