The LoggerContextRule when used with JUnit @Rule annotation to provide isolation between tests only logs the first test successfully. Subsequent tests do not log at all.
The issue appears to be with the call to `Configurator.shutdown(context);`. It seems to prevent future calls to `Configurator.initialize(...` from working properly. I have not seen any indication that repeated cycles of calls to `Configurator.initialize` and `Configurator.shutdown` should not create working contexts.
As a test, I removed Configurator.shutdown and this resulted in the expected behavior. I assume that is not a legitimate fix seeing that it would leak active contexts.
