我们正在将Struts2用于企业应用程序，但由于NPE而崩溃。操作的错误处理方法中出现异常。我的猜测是，它试图递归调用错误处理方法，因为当它尝试处理错误时，它每次都会获得一个新的 NPE。然后 JVM 崩溃。
但我的问题是，这可能是崩溃的真正原因吗，递归异常会导致 JVM 崩溃吗？JVM发现自己处于什么类型的情况，此异常如何影响线程状态？如您所见，我对 JVM 如何处理线程的信息不是很多。感谢您的回复。
有好的一天。
编辑：对不起，伙计们，这是我得到的堆栈跟踪的一部分。堆栈跟踪无休止地重复自己。

正如
我所怀疑的那样。错误处理周期会导致递归NPE，正如Polygnome所说，JVM由于StackOverflowError或OutOfMemoryError而崩溃。无论如何，谢谢大家。
