JMeter starts with warning message

I have JMeter set-up on my Windows 8 machine. When I startup JMeter it starts fine but leaves a warning message that I could not understand why.

Here is the log that I see in the command prompt:

C:\Users\Ayusman>jmeter
Dec 20, 2013 12:52:57 PM java.util.prefs.WindowsPreferences <init>
WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs at root 0x80000002. Windows RegCreateKeyEx(...) returned error code 5.

Is any body aware what could be the issue? I did check the registry information HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft and I do not see a "Prefs" folder in there. But am I supposed to create a registry entry there?

System Information:

Windows 8, 32 bit.
JMeter Version: 2.10
Java Version: 1.7.0_25

Thanks.

Solution

As @michali mentioned in the comment. Creating a new key "Prefs" under "HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft" in Windows registry editor after logging in as administrator did solve the problem. However JMeter does not create or write anything under this key. Not sure why.
