27 | * The "old API" works by attaching a handler managed by the agent to | |
da8308fe | 28 | * the root JUL logger. This causes problems here, because we use |

29 | * logger.setUserParentHandler(false), which does not trigger the |
30 | * handler as would be expected. | |
31 | * | |
32 | * Instead we will retrieve this handler through reflection, and attach | |
33 | * it to our own logger here for the duration of the test. | |
