             Summary: LogTest loses its spy handler when the logger is garbage 
collected before the class under test logs
                 Key: GROOVY-12573
                 URL: https://issues.apache.org/jira/browse/GROOVY-12573
             Project: Groovy
          Issue Type: Test
            Reporter: Scott Murphy Heiberg


{{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).
