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.

Solution

  • Dennis answer is correct. However I would like to explain the solution in a bit more detailed way (for Windows User):

    1. Go into your Start Menu and type regedit into the search field.
    2. Navigate to path HKEY_LOCAL_MACHINE\Software\JavaSoft (Windows 10 seems to now have this here: HKEY_LOCAL_MACHINE\Software\WOW6432Node\JavaSoft)
    3. Right click on the JavaSoft folder and click on New -> Key
    4. Name the new Key Prefs and everything should work.

    Alternatively, save and execute a *.reg file with the following content:

    Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs]
