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

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. 9 Answers 9
