栈溢出

虚拟机栈和本地方法栈有下面两种异常：

线程请求的栈深度大于虚拟机允许最大栈深度，抛StackOverflowError

虚拟机栈扩展时无法申请到足够的空间，抛OutOfMemoryError

public class Test {public int stackLength = 1;public void stackLeak(){stackLength++;stackLeak();}/** * @param args */public static void main(String[] args) {// TODO Auto-generated method stubTest t = new Test();try{t.stackLeak();} catch(Throwable e){System.out.print("stack legth:\n"+t.stackLength);throw e;}}}

参数设定

-verbose:gc  -Xss1M -XX:+HeapDumpOnOutOfMemoryError -XX:SurvivorRatio=8

运行结果

stack legth:29272
Exception in thread "main" java.lang.StackOverflowError
