> {{LogTest.registerLogFormatterSpy}} adds a handler to 
> {{Logger.getLogger(name)}} without keeping the logger. The {{LogManager}} 
> holds loggers weakly, so a garbage collection before the class under test 
> initializes drops the logger, and the class gets a new one without the spy; 
> {{testDefaultCategory}} then fails (seen on CI).
