    Could not initialize class javax.swing.UIManager

      Dear all,
      I'm newbie of java technology.
      I need your help to solve my issue.
      I developed a Java fx application and I run it with:

      javafx -classpath application.jar application.Main

      It works on every win 7 system.

      On some xp system (not everyone, only some one) I got this exception:
      java.lang.noclassdeffounderror: Could not initialize class javax.swing.UIManager
      line on which error appears is the following
      for (info: LookAndFeelInfo in UIManager.getInstalledLookAndFeels()) {

      from this code
      // use NIMBUS look
          try {
              for (info: LookAndFeelInfo in UIManager.getInstalledLookAndFeels()) {
                  if ("Nimbus".equals(info.getName())) {
          } catch (cEx: Exception) {
      Could you please help me??
      I'm desperate...I can't reproduce error on each xp system, because on most of them application works...only on some xp system it appears.
      I tried to uninstall jre and install latest one and I also updated graphic drivers to latest one.

      I hope someone can help me...I can't solve it and I'm crazying.

      Thanks in advance
