Java console loop

Question

Noticed no one has answered this yet on here so thought I'd give it a shot again. Hopefully someone can help. Already went to my Java teacher and he just said I messed something up and couldn't figure it out so I can't move on.

Anywho, here's my test code:

import javax.swing.JOptionPane;

public class Test {

    public static void main(String[] args) {
        System.out.println("hello");
        JOptionPane.showInputDialog("Enter a real number");
    }
}

And this is what I receive in console:

hello

03:30.28 1[dbg] In DllGetClassObject
03:30.28 2[dbg] CShellExtClassFactory::CShellExtClassFactory()
03:30.28 3[dbg] CShellExtClassFactory::QueryInterface()
03:30.28 4[dbg] CShellExtClassFactory::CreateInstance()
03:30.28 5[dbg] CShellExt::CShellExt()
03:30.28 6[dbg] Looping before Zumo is running
03:30.28 7[dbg] CShellExt::QueryInterface()==>IID_IShellIconOverlayIdentifier
03:30.28 8[dbg] CShellExt::AddRef()
03:30.28 9[dbg] CShellExt::AddRef()
03:30.28 10[dbg] CShellExt::Release()
03:30.28 11[dbg] CShellExt::QueryInterface()==>IID_IShellIconOverlayIdentifier
03:30.28 12[dbg] CShellExt::AddRef()
03:30.28 13[dbg] CShellExt::Release()
03:30.28 14[dbg] Entering CShellExt::GetOverlayInfo
03:30.28 15[dbg] Icon path: C:\Program Files (x86)\Hewlett-Packard\HP CloudDrive\icons\deflated.ico
03:30.28 16[dbg] Exiting CShellExt::GetOverlayInfo successfully.

Any help would greatly be appreciated. I have already tried re installing everything I could which include eclipse and the JDK 1.7. I also noticed this only happens when I try to use the dialog JOptionPane so far. I am using a windows 7 system.

Thanks guys

Works for me too (Windows 7/Java 7/IntelliJ). What is that JNI rubbish from HP CloudDrive? Is that related to the question? — Mikkel Løkke

This thread mentions a similar problem : area.autodesk.com/forum/autodesk-maya/… It seems uninstalling ZumoCast was the solution. — alain.janinm

Just a guess, because I have ran into strange AWT/Swing issues on other systems, you could try this here (sometimes the underlying UI system gets not initialized properly, but as I said, this is just a guess):

public class Test 
{
    public static void main(String[] args) 
    {
        SwingUtilities.invokeLater(new Runnable()
        {
            @Override
            public void run()
            {
                System.out.println("hello");
                JOptionPane.showInputDialog("Enter a real number");
            }
        });
    }
}

By using invokeLater you force the whole UI system to get initialized (the EDT to be started and the option pane showed from inside the EDT), I had to use this trick e.g. for getting my SDL bindings under OSX to work. invokeLater initializes the whole Cocoa system for me.

That certainly should be done, whether it solves this problem or not.

Guys I just wanted to say THANK YOU to everyone who replied because it was very fast as well as it helped me solve the situation. The solution ended up being a pre-installed software called Hp Cloud drive which is just a sub-title for the Zumo(same developers) After I uninstalled it, I do not get that horrendous mass of code. Everything works fine.// My suggestion to anyone having this problem is to check to see if you have a cloud software of some kind. Anyways thanks again everyone. I read every comment and used it in a trial and error process until I found the solution. Greatly appreciated.

This occurred to me too when I had a JTextField or JTextArea showing in my program. It only occurred when compiling and running on Java 7 or higher, but not on Java 6.

I don't know why it was happening, but uninstalling HP CloudDrive, a program which came pre-installed on my HP laptop, stopped all those lines showing up.
