JDBC操作偶尔碰到这样的异常： java.sql.BatchUpdateException: Overflow Exception trying to bind NaN
在Sun的Java论坛上有人解释，当把一个非法的数字（如“0f/0f”）绑定到一个字段，执行Update操作就会报这样的错误，如下：
It looks like you did some bad arithmetic, resulting in a "Not A Number" (NaN) result. For example:
public class Nan {
public static void main(String[] args) {
float nan = 0f / 0f;
System.out.println(nan);
}
}
When you then try to store that value in a floating point column, the database complains. So the problem is in your Java logic, and the database is trying to prevent you from corrupting the column!
It's not specific to the BatchUpdate, it just happened to occur in one, and so the BatchUpdate had to report the error.
Java应用程序有时候会异常的崩溃，并在桌面或某个目录产生例如hs_err_pid2160.log文件，里面的内容如：
#
# An unexpected error has been detected by HotSpot Virtual Machine:
#
# EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x6d0d1dda, pid=2160, tid=2812
#
# Java VM: Java HotSpot(TM) Client VM (1.5.0_06-b05 mixed mode, sharing)
# Problematic frame:

或者：
shell> mysqld_safe --character-set-server=utf8
一份由Indiian Instiitute off Management,Ahmedabad发布的名为“Java Economy in India: A Pessimistic Estimate”的分析报告称：
估计2005年的印度Java经济的总量约$112.7亿，2006年的印度Java经济总量约$146.5亿，而Java经济占了印度GDP（国民生产总值）2.1%。
