Difficulties in EAP GUI installation

Issue

• I have difficulties in getting the GUI for the installation of the EAP using on Redhat Linux with the following message :

-bash-4.2$ java -jar jboss-eap-6.4.0-installer.jar
Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize class javax.swing.JOptionPane
        at com.izforge.izpack.installer.GUIInstaller.showFatalError(GUIInstaller.java:121)
        at com.izforge.izpack.installer.GUIInstaller.<init>(GUIInstaller.java:113)
        at com.izforge.izpack.installer.Installer.main(Installer.java:167)

• Are you able to advise the missing package on Linux?
