--------------------------------------

Hi Vladimir,

sorry for the delayed response (back from holidays and too much to do :().
But now, I have a simpel test case.

I wrote a test WAR that can be build with maven.
Deploy it to jboss-as-7.1.1.Final an call http://localhost:8080/map-reduce-bug-as7/rest/count.

Result is:

java.lang.ClassCastException: org.infinispan.marshall.MarshalledValue cannot be cast to com.example.mapreducebugas7.TestEntry
	com.example.mapreducebugas7.CountMapper.map(CountMapper.java:1)
	org.infinispan.commands.read.MapReduceCommand.perform(MapReduceCommand.java:150)
	org.infinispan.distexec.mapreduce.MapReduceTask.execute(MapReduceTask.java:286)
	org.infinispan.distexec.mapreduce.MapReduceTask.execute(MapReduceTask.java:367)
	com.example.mapreducebugas7.CountResource.count(CountResource.java:31)

clone: https://github.com/xandrox/map-reduce-bug-as7
mvn install
copy to standalone/deployments
start "bin/standalone.sh -c standalone-full-ha.xml"

standalone-full-ha.xml can be found in the root of the git project...
Look at com.example.mapreducebugas7.CountResource to see the simple count logic.

Good luck!
Cheers Sandro
