I was having the same issue with ClearOS 6 installation, which is based off from CentOS.  I was able to fix it by installing libgcc.  

yum install libgcc_s.so.1

I also modified the run.sh file to set the font render into a headless mode.

jre/bin/java -server -Xmx512m -cp $CP -DLoggingConfigFile=logconfig.xml -Djava.awt.headless=true com.synametrics.xeams.ServerStarter
