I’m seeing this NPE:
CreateMonDI nodeId=ns=2;s=nestedVar.nestedMbr.dintMbrc.size()=1
09/28/2012 10:18:40.643 ERROR PublishRequestQueueHandler.run
java.lang.NullPointerException

at com.prosysopc.ua.server.SubscriptionServiceHandler$b.run(Unknown Source)
at java.lang.Thread.run(Thread.java:722)
It seems to only happen when I’m running the server on Debian. On Windows it doesn’t happen.
I’m seeing this when the client subscribes to a nested data item. You can see the path in the previous line.
What would cause an NPE in the a() method?
