I experienced a similar error. I think its related to bug 23487. It looks like the
code applied to fix it wasn't applied to the ClientJmeterEngine and thus only effects
remote testing. I added the following code
sampleListeners = new ConvertListeners();
//TODO this is a temporary fix - see bug 23487
try {
getTestTree().traverse(sampleListeners);
}
catch(IndexOutOfBoundsException e)
{
log.warn("Error replacing sample listeners",e);
}

Subject: java.lang.NullPointerException at

Using JMeter 2.0.1 with 2 remote servers all running jrockit 1.4.2 under
Linux (RH AS2.1, I think).
I am seeing a ton of these errors on startup:
java.lang.NullPointerException
at
org.apache.jmeter.engine.ConvertListeners.addNode(Ljava.lang.Object;Lorg.apa
che.jorphan.collections.HashTree;)V(ConvertListeners.java:54)

at java.lang.Thread.run()V(Unknown Source)
at java.lang.Thread.startThreadFromVM(Ljava.lang.Thread;)V(Unknown
Source)
When I had seen and reported them previously (1.8 or 1.9), the one remote
server that it occurred on would fail to start, but the rest of the test
would run. Now, the whole test hangs (which I guess is preferable). I will
get these errors on one server, then the other, then back again, seemingly
at random. And then it will work. All this without either changing the
test plan, or restarting the remote servers (i.e. it's intermittent and
random). If I use a less powerful controller, though, it all works fine,
first time. Any ideas?
Thanks!
