[jira] Reopened: (TUSCANY-2069) Missing serialization in
DirectedGraph

Mark Combellack reopened TUSCANY-2069:
--------------------------------------
The fix is actually causing a Null PointerException in the Unit Tests for databinding.

This is caused by the type of the collection chainging from HashMap to ConcurrentHashMap. The difference is that a HashMap will allow null key and values whereas a ConcurrentHashMap does not.
The test is attempting to add a null as a value for one of the keys.
To get this to build, I am going to add a null check around the offending point so it does not attempt to put a null in the ConcurrentHashMap.

> 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.
