Groovy Shell warning “Could not open/create prefs root node …”

by

I tried to open the Groovy Shell (groovysh) on Windows 8 and got the following output:

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.

After printing the above message the shell started as expected.
