NullPointerExceptions when enabling the plugin in Default Settings

[loloakira]

On Webstorm 9.0.3, when i try to enable and configure the jscs plugin in the default Settings part, i've got a "NullPointerException : null" Error. It's possible to reproduce just going into the "Default Settings" panel, in "Other Settings", select the JSCS menu and enable the plugin. Then, select the Node interpreter. It always throws the exception.

Detail of the error :
