Failed to write core dump. Minidumps are not enabled by default on client versions of Windows

使用JProfiler监控JAVA程序内存，JVM报错：

A fatal error has been detected by the Java Runtime Environment:

原因：
Minidump是Windows上的程序crash的时候可以写出的一种小型crash dump，会记录导致crash的错误的摘要信息，以便开发者可以事后调查crash的原因。HotSpot VM在非server版的（也就是client版的）Windows上选择默认不写出minidump。

解决：
要让HotSpot VM在client版Windows上写出minidump，请指定 -XX:+CreateMinidumpOnCrash，这样HotSpot VM在crash时就会调用Windows的MiniDumpWriteDump()函数写出minidump。
