The compiler in the server VM now provides correct stack backtraces for all "cold" built-in exceptions. For performance purposes, when such an exception is thrown a few times, the method may be recompiled. After recompilation, the compiler may choose a faster tactic using preallocated exceptions that do not provide a stack trace. To disable completely the use of preallocated exceptions, use this new flag: -XX:-OmitStackTraceInFastThrow.
PS. 最关键的并不是堆栈被JVM吃掉，而代码里面对异常应该怎么样被合理的处理，没有一个清晰的想法，而只是简单地打印堆栈，这是值得好好思考的。
