#2 NullPointerException when running on application server

[Olexiy Leonov]

NullPointerException in com.lowagie.text.rtf.parser.destinations.RtfDestinationFontTable.importSystemFonts()
OS: AIX 6.1
Application Server: JBoss 4.2.3.GA

RtfDestinationFontTable.getEnvironmentVariables method throws exception when running in managed environment under application server.
so line "String systemRoot = pr.getProperty("SystemRoot");" causes NullPointerException cause Properties pr aren't initialized.
We use folowing fix:
com.lowagie.text.rtf.parser.destinations.RtfDestinationFontTable.importSystemFonts:

private void importSystemFonts() {
   Properties pr = null;
   try {
      pr = getEnvironmentVariables();
   } catch (Throwable e) {
   }
   if (null != pr)
   {
      String systemRoot = pr.getProperty("SystemRoot");
      String fileSeperator = System.getProperty("file.separator");
      FontFactory.registerDirectory(systemRoot + fileSeperator + "fonts");
   }
}
