Raymond Feng reassigned TUSCANY-2069:
-------------------------------------
Assignee: Raymond Feng
> Missing serialization in DirectedGraph
> --------------------------------------
>
> Key: TUSCANY-2069
> URL: https://issues.apache.org/jira/browse/TUSCANY-2069
> Project: Tuscany
> Issue Type: Bug
> Components: Java SCA Data Binding Runtime
> Affects Versions: Java-SCA-1.0.1
> Reporter: Greg Dritschler
> Assignee: Raymond Feng
> Fix For: Java-SCA-Next
>
>
> I have a service with a web service binding that processes its input using an
> SDO. The service works fine with one client. It also works fine if it is
> driven once by one client and then driven by multiple clients. But if it is
> driven initially by multiple clients (2 is enough), various failures occur in
> org.apache.tuscany.sca.databinding.impl.DirectedGraph. It appears there is a
> lack of synchronization in this class.
> Failure 1 - NPE
> java.lang.NullPointerException
