Hi,I'd like to update some findings.
My compouter runs CentOS 6.4 x64, and I install openjdk 1.8 x86_64, then I find the problem went away. :) The former openJRE is from another computer which runs CentOS 6.6 x86, and I installed openjdk 1.8 and copied the jre folder to my project as part of installation. I hope this jre folder can runs everywhere, and I don't know if it loses some libraries. Actually I copied following 3 libraries to jre i386 directory in order make it runs. 1. libfreetype.so 2. libfontconfig.so 3. libexpat.so Indeed it runs well most time except this jfreechart issue. I guess it still miss some libraries. But I'm not sure. Who can help with it ? As to why I copy existing jre foler rather than install a new openjre because Oracle JRE is a tar file and I like it. I used to embed all necessary parts into project and so I won't ask customer to install this or that dependency part. ------------------ Original ------------------ From: "AAAA";<31731...@qq.com>; Date: Sat, May 7, 2016 12:19 PM To: "awt-dev"<awt-dev@openjdk.java.net>; Subject: <AWT Dev> An issue of OpenJRE If this mail distrub you please ignore that, sorry for inconveniences. I really hope to get your help. Recently I'm porting a project form oracle jdk to open jdk, and compile process is smooth and most parts runs well, but jfreechart cannot work. I have submitted a question to jfreechart forum (http://www.jfree.org/forum/viewtopic.php?f=3&t=117569&p=179724#p179724). However after sometime troubleshooting, I find the problem is related with open jre. That means jfreechart works fine in oracle jre but fails in open jre. Again I find more details, when I run following codes I will get wrong result, which causes jfreechart not to work. BufferedImage image = new BufferedImage(200, 200, BufferedImage.TYPE_INT_RGB); Graphics2D g2 = image.createGraphics(); FontMetrics fm = g2.getFontMetrics(); The fm includes strange value, if I switch to oracle jre fm has right value. I don't know why. Can somebody help me?
