| [jetty-users] Baffling nullpointer on a LOG statement? |
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:
2012-09-28 07:27:03,551 | WARN | stackref=13a0b579cf2
