Description
It was designed that wmic is called only once to obtain the system environmental data.  Apparently, at every NetBeans IDE startup, wmic is invoked 5 times repeatedly. It is called on every call of RegistrationData.loadFromXML().

EVALUATION The RegistrationData() should only call the initEnvironment() method when creating a brand new RegistrationData object but not loading from a XML file.
