<AWT Dev> An issue of OpenJRE

Hi Dalibor,


Actually this time I download OpenJDK source code and build it myself, but I still met this issue. I wonder why font files in jre/lib/fonts folder impact openjre.


Here is a brief of this problem, I try to decribe it clearly.


I build OpenJDK, and copy j2re-image to my folder such as /home/rong/jre, and use this jre to run my java applicaton. In further study I have found following codes, fm will have wrong value as long as jre/lib/fonts has font files (some ttf files).


	        BufferedImage image = new BufferedImage(200, 200, BufferedImage.TYPE_INT_RGB);
	        Graphics2D g2 = image.createGraphics();
	        FontMetrics fm = g2.getFontMetrics();


But if I moved these font files into /usr/share/fonts folder, the problems goes away. I'm not sure why these font files impact open jre run time.
I don't think this problem is related to centos.


BTW, I have installed freetype and fontconfig package.



Regards,
Rong

If you have encountered problems with binaries provided by CentOS, 
you'll need to contact CentOS for support.
