------------------------------------

Thanks for the quick response.

It occurred in 2.4.1.

I use  JMS as the transport protocol wich serializes whole org.jgroups.Message objects into a JMS ObjectMessage. I think during this process writeExternal()/readExternal() is called? writeUTF() simply throws a NullPointerException if the String object is null.
BTW: I'm stuck with JDK 1.4.2, so upgrading to 2.5 is not an option for me...

> The pbcast.STATE_TRANSFER.StateHeader class does not check if state_id is null during serialization. This leads in my case to a NullPointerException which stops the complete state transfer and results in two members that are not in sync.
