Can't load standard profile: GRAY.pf

今天项目中遇到一个异常，异常代码如下：

 这里省略更多异常代码。。。。。看了半天不知道什么问题，只知道自己代码用用了一个类功能是出来图片大小的，如果图片太大压缩到固定大写。

import java.awt.Image;

		this.outputHeight = outputHeight;
	}

	public void setWidthAndHeight(int width, int height) {

	}

 在应用中用到如下语句就出错

ImageCompress ic = new ImageCompress();
ic.compress(uploadPath,reloadPath,500, 450, true);

 后来网上找了下，说是jdk问题，具体原因不知，说是在jdk安装目录“C:\Program Files (x86)\Java\jdk1.6.0_10\jre\lib\cmm”下找不到GRAY.pf文件，查看路径确实没有该文件，重新安装jdk后，赶快跑到C:\Program Files (x86)\Java\jdk1.6.0_10\jre\lib\cmm下查看是否有GRAY.pf文件，确实重装jdk后有该文件。
