We are using:

OPC UA Client:
Prosys-OPC-UA-Java-SDK-Client-Binary-2.3.0-764.jar
Opc.Ua.Stack-1.02.337.12.jar

OPC UA Server:
prosys-opc-ua-simulation-server-windows-x64-5.0.2-242.exe

We are calling getNode() (well, or getType()) on i=47 (which happens to be ReferenceType “HasComponent”) and then we get this:

Exception in thread “TcpConnection/Read” java.lang.IllegalArgumentException: Value underflow

And in the following, the actual calling thread runs into this:

com.prosysopc.ua.ServiceException: Bad_Timeout (code=0x800A0000, description=”The operation timed out.”)

Any explanation on this? Known Bug in Client? (see Version above), Update opc-ua-stack? From where?

THANK YOU!
