- Method Detail
  - getLoggerContext
```
public static ch.qos.logback.classic.LoggerContext getLoggerContext()
```
    Acquires the logger context.
    
    It tries to correctly acquire the logger context in the multi-threaded environment. Because of the http://jira.qos.ch/browse/SLF4J-167 a thread, that didn't start initialization has a possibility to get a reference not to a real context, but to a substitute.
    
    To work around this bug we spin-loop the thread with a sensible timeout, while the context is not initialized. We can't just make this method synchronized, because LoggerFactory.getILoggerFactory doesn't safely publish own state. Threads can observe a stale state, even if the logger has been already initialized. That's why this method is not thread-safe, but it makes the best effort to return the correct result in the multi-threaded environment.
  - hijackJDKLogging
```
public static void hijackJDKLogging()
```
    Gets the root j.u.l.Logger and removes all registered handlers then redirects all active j.u.l. to SLF4J
    N.B. This should only happen once, hence the flag and locking
