I hate to say this Bruce, but unfortunately 3.2.2 is working pretty bad for
me and has the same problem :( It only seems to affect our production
server and in a few minutes after start up, I start getting the
NullPointerException.. slowly all my services start doing it and they all
stop working. If I stop and restart servicemix, then servicemix-jms
components are no longer routable. I'm guessing this error causes
Servicemix to shut them down and not deploy them anymore (Servicemix does
the same thing if a service unit starts up, tries to make a Joram connection
to a server that isn't up, servicemix will shutdown that SU and will always
shut it down immediately after it starts on any subsequent run).
It seems like this problem must be related to a race condition. When doing
development testing, I never see this problem on my laptop even under high
load. One our fast test server, I see this error popup once on startup and
then it doesn't seem to happen again. On our even faster production server,
the whole thing looses it's wheels and falls apart after a few minutes.
I'm supposed to be deploying this system in a few days and of course that's
the only spot where I can't temporarily limp by. Is it possible you could
give me some hints on what the problem is and I'll debug it this weekend to
see if I can fix it, or at least patch it temporarily? I really need to
figure out way to get around this problem. Other than that, 3.2.2 seems to
work perfectly fine.
Here is the caused by error again in case it's any bit different than the
3.2.1 one was:
Caused by: java.lang.NullPointerException
at
java.util.concurrent.ConcurrentHashMap.put(ConcurrentHashMap.java:881)
at
org.apache.servicemix.bean.BeanEndpoint$PojoChannel.send(BeanEndpoint.java:569)
at
com.notification.impl.JbiNotificationHandlerImpl.sendNotification(JbiNotificat
ionHandlerImpl.java:80)
Also, is the delivery channel component threadsafe? I'm curious if multiple
threads accessing it is a problem or if I should keep access to it
synchronized? I'm currently synchronizing, but don't want to if I don't
need to.
Thanks!
