NoSuchElementException in Hot Rod Encoder ----------------------------------------- Key: ISPN-2550 URL: https://issues.jboss.org/browse/ISPN-2550 Project: Infinispan Issue Type: Bug Components: Remote protocols Affects Versions: 5.2.0.Beta4 Reporter: Michal Linhard Assignee: Dan Berindei Priority: Blocker Fix For: 5.2.0.Beta6 Tomas noticed this a while ago in a specific functional test: https://bugzilla.redhat.com/show_bug.cgi?id=875151 I'm creating a more general JIRA, cause I'm having this in resilience test. What I found by quick debug, is that here: https://github.com/infinispan/infinispan/blob/master/server/hotrod/src/ma... {code} for (segmentIdx <- 0 until numSegments) { val denormalizedSegmentHashIds = allDenormalizedHashIds(segmentIdx) val segmentOwners = ch.locateOwnersForSegment(segmentIdx) for (ownerIdx <- 0 until segmentOwners.length) { val address = segmentOwners(ownerIdx % segmentOwners.size) 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.
