HP LoadRunner (wlrun) always exit with status 1

I am trying to run HP LoadRunner (wlrun.exe) command from Java Program and check the status at the exit of wlrun.exe command.

Sample Java Code:

 public class LRTest
 {
   private static int exitValue = -1;
   private class WlRunExecution extends Thread
   {
     Process p;
     String command = new String();
     public WlRunExecution(String command)
     {
       this.command = command;
     }
     public void run()
     {
       LRTest.exitValue = -1;
       try
       {
         this.p = Runtime.getRuntime().exec(this.command);
         while (IsLoadRunnerRunning())
         {
           Thread.sleep(1000L);
         }
       }
       catch (Exception e)
       {
         System.out.println(e);
       }
     }
     public boolean IsLoadRunnerRunning()
     {
       boolean IsLoadRunnerRunning = false;
       try
       {
         LRTest.exitValue = this.p.exitValue();
       }
       catch (IllegalThreadStateException e)
       {
         IsLoadRunnerRunning = true;
       }
       return IsLoadRunnerRunning;
     }
    }
   public static void main(String[] arg)
   {
       LRTest test = new LRTest();
       test.runTest();
   }
   public void runTest()
   {
     WlRunExecution process = null;
     String command = "\"C:\\Program Files (x86)\\HP\\LoadRunner\\bin\\Wlrun.exe\"  -Run -TestPath  \"C:\\Test\\LoadRunner\\TestBing\\ScenarioBing.lrs\" -ResultName \"C:\\Test\\LoadRunner\\TestBing\\LRResult\"";
     //String command = "\"C:\\Program Files (x86)\\HP\\LoadRunner\\bin\\Wlrun.exe\"";
     try
     {
         process = new WlRunExecution(command);
         Thread t = new Thread(process);
         t.start();
         t.join();
         System.out.println("Process Exit code : " + exitValue);
     }
     catch (Exception e)
     {
       System.out.println(e.getMessage() + e);
     }
   }
 }

On running the program, **Process Exit Code is always 1** which means wlrun process is exited with some error. Even if I run "wlrun" without any argument and manually close the LoadRunner Controller after launch, still process exit code is 1. If I replace "wlrun.exe" with any other command (notepad,exe or AnalysisUI.exe or VuGen.exe) then Process Exit Code is 0.

On debugging, I observed following error in Application Event Logs (Control Panel -> Administrator Tools -> Computer Management -> Event Viewer -> Windows Logs -> Application). Everytime I run HP LoadRunner Controller, this warning is logged in application event log.

HP.LT.Logger configuration failed creating context provider of the type: HP.PC.Security.SSO.AppContextLoggingProvider, HP.PC.Security.SSO

Please help in resolving this issue.
