[EC76] rule improvment : static list not so bad

[dedece35]

Describe the bug
EC76 rule wants us to avoid usage of static list in a class but as in use case below, list can be static or not because a singleton class is instanciated one time by spring context and destroyed when application is down. Thus static way or not, the list is really declared one time and the garbage collector doesn't have to clean it.
I think this rule have to be proved and measured to confirm its veracity.
