Somehow the LOG object itself is null.
Not sure how that's possible.
The Log.getLogger() is wired up on first access.


Try setting up the Logger manually.
At the earliest point you can in your code, set the Logger implementation.

Log.setLogger(new StdErrLog()); or
Log.setLogger(new Slf4jLog()); or
Log.setLogger(new JavaUtilLog());

Any committers can help me understand how this could happen? I'm seeing a
null pointer at a logging statement at line 199 in AbstractLifeCycle:

        LOG.warn(FAILED+" " + this+": "+th,th);


I'm looking at    <jetty-version>7.6.1.v20120215</jetty-version>

The code for how we are starting the jetty server is here (line 146):

http://svn.apache.org/viewvc/activemq/activemq-apollo/trunk/apollo-broker/src/main/scala/org/apache/activemq/apollo/broker/jetty/WebSocketTransportFactory.scala?view=markup

And I see this stack trace:
