problem with remote classloading

Hello,
I'm using SF 3.06.000_rc1. I wrote a component extending EventPrimImpl. It 
sends an event to some other component and this works fine when I place 
the jar containing the component into $SFHOME/lib. The LogLevel=2 output 
on the sender side is:

EventSender starting to send an object 
ch.cern.openlab.smartfrog.pbs.PBSnodeAdd
2005/06/22 17:25:10:402 CEST [DEBUG][RMI TCP Connection(2)-137.138.38.90] 
HOST oplapro34.cern.ch:rootProcess:pbsNodeEventSender - HOST 
oplapro34.cern.ch:rootProcess:pbsNodeEventSender:send sending 
ch.cern.openlab.smartfrog.pbs.PBSnodeAdd@53fcc0a2 to 
ch.cern.openlab.smartfrog.pbs.PBSserverWatcher_Stub[RemoteStub [ref: 
[endpoint:[137.138.38.90:39682](remote),objID:[6345e044:104a4a66844:-8000, 
4]]]]

Now I want to get the jar from a web server instead of copying it into 
$SFHOME/lib. I enable SFDYNAMICCLASSLOADING_ON. Deploying the component 
works, i.e. it gets the class from the jar on the web server (I removed 
the jar in $SFHOME/lib) but sendEvent no longer works. The log output is:

EventSender starting to send an object 
ch.cern.openlab.smartfrog.pbs.PBSnodeAdd
2005/06/22 17:22:29:313 CEST [ERROR][RMI TCP Connection(2)-137.138.38.90] 
HOST oplapro34.cern.ch:rootProcess:pbsNodeEventSender - Failed to send 
event: ch.cern.openlab.smartfrog.pbs.PBSnodeAdd@35f03691[class 
ch.cern.openlab.smartfrog.pbs.PBSnodeAdd], cause: null 
<java.lang.NullPointerException>

What could be the problem ? I don't know why sendEvent no longer works 
with remote class loading. Thanks !

Best regards,
Andreas
