@daniellansun Merged master, which starts a new CI run (a fork author cannot
re-run jobs).
> LogTest loses its spy handler when the logger is garbage collected before the
> class under test logs

> Project: Groovy
> Issue Type: Test
> Reporter: Scott Murphy Heiberg
> Priority: Major
>
> {{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).
