svn commit: r1061851 - in /tuscany/sca-java-2.x/trunk: modules/core/src/main/java/org/apache/tuscany/sca/core/assembly/impl/ modules/core/src/main/java/org/apache/tuscany/sca/core/invocation/ samples/extending-tuscany/implementation-sample/src/main/jav...

Author: slaws

New Revision: 1061851

URL: http://svn.apache.org/viewvc?rev=1061851&view=rev
Log:
TUSCANY-3783 - Fix a hole in the AsyncReponseInvoker serialization to cover the case there invoker is de-serialized inside the same context that serialized it. Update the sample to demonstrate a stop/start scenario.
