Hi Galder,

I experience this problem in our functional test suite for remote mode (server).

preNOTE: you probably don'e need to install Arquillian project as it's CR1 is published already.
preNOTE: you need to create empty directory with name "bundles" in edg0/ edg1/ etc.

Please see this doc: https://docspace.corp.redhat.com/docs/DOC-87715
Download our tests from svn and run this specific test. (for storage only example)

Just sink to edgTest/trunk/remote and run

 mvn -s ~/programs/eclipseWorkspace/settings_mead_jdg_plus_local.xml  clean verify -Dstack=udp -pl config-examples/standalone-storage-only  -Dnode0.edghome=/home/tsykora/edg0 -Dnode1.edghome=/home/tsykora/edg1 -Dnode2.edghome=/home/tsykora/edg2 -Dmaven.test.failure.ignore=true 

NOTE: this user specific mvn setting file (-s) is pointing to my "local" repo which is comming with regular ER builds. You can ignore it and simply run this with these settings using MEAD repo:

https://svn.devel.redhat.com/repos/jboss-qa/jdg/scripts/settings_mead_jdg.xml

You can obtain latest JDG server from here: http://download.lab.bos.redhat.com/devel/jdg/stage/JDG-6.1.0-ER5/

I hope I didn't forget anything. In case of any problem, anything, let me know.

> Tomas noticed this a while ago in a specific functional test:

> I'm creating a more general JIRA, cause I'm having this in resilience test.
> What I found by quick debug, is that here:

> {code}
>                for (segmentIdx <- 0 until numSegments) {
>                   val denormalizedSegmentHashIds = allDenormalizedHashIds(segmentIdx)
>                   val segmentOwners = ch.locateOwnersForSegment(segmentIdx)

>                      val serverAddress = members(address)
>                      val hashId = denormalizedSegmentHashIds(ownerIdx)
>                      log.tracef("Writing hash id %d for %s:%s", hashId, serverAddress.host, serverAddress.port)
>                      writeString(serverAddress.host, buf)
>                      writeUnsignedShort(serverAddress.port, buf)
>                      buf.writeInt(hashId)
>                   }
>                }
> {code}
> we're trying to obtain serverAddress for nonexistent address and NoSuchElementException is not handled properly.
> It hapens after I kill a node in a resilience test and the exception appears when querying for the node in the members cache.
