如何在IBM Bluemix Delivery Pipeline中调试未处理的异常/分段错误

Question

我在IBM Bluemix DevOps中创建了一个工具链，并且它有一个Delivery Pipeline应用程序。 在我试图安装和运行SBT的阶段，但我面临着一个问题。不幸的是，根据日志我无法弄清楚问题所在，它只是告诉我们发生了未处理的异常，分割错误和某种内部堆栈跟踪。

我该如何调试容器中发生的事情属于这个工作？

这里的作业控制台日志：

Answer 1

，我的建议是要提高通过Bluemix获得支持凭单。

Answer 2

从日志看来，当它试图编译scala/collection/mutable/FlatHashTable.addElem（Ljava/lang/Object;）时，JIT崩溃。您可以尝试从JIT编译中排除此方法，并查看该作业是否通过。使用此JVM选项：

-Xjit：排除= {斯卡拉/收集/可变/ FlatHashTable.addElem}，dontInline = {斯卡拉/收集/可变/ FlatHashTable.addElem *} *

如果这个作品，问题出在Java JIT上，你应该向IBM提出一张票。
