Issue description
JPPF node with Xstream serialization fails to connect to JPPF driver. The following exception occurs:

Steps to reproduce this issue
Cluster is made of one driver and one node instance. Both driver and a node have out-of-box configuration, except for one line jppf.object.serialization.class = org.jppf.serialization.XstreamSerialization which is uncommented on both entities.

Jars xstream-1.4.11.1.jar and xpp3-1.1.4c.jar were downloaded into the lib folder of a driver and a node.

In fact, from the latest XStream distro, I found that these 3 jars are required: xstream-1.4.11.1.jar, xpp3_min-1.1.4c.jar, xmlpull-1.1.3.1.jar

Flushing the ObjectOutputStream created by XStream, after writing the object in XstreamSerialization.serialize(), appears to fix the problem.

I will add non-regression tests for XStream (the same as for standard Java, JPPF and Kryo serializations) to ensure this kind of problem is detected ASAP.

It seems there is an issue with the deserialization of javax.management.Notification objects with XStream. I created xstream issue #135 for this.
