Remote iterator does not work in compatibility mode --------------------------------------------------- Key: ISPN-6550 URL: https://issues.jboss.org/browse/ISPN-6550 Project: Infinispan Issue Type: Bug Components: Server Reporter: Gustavo Fernandes Assignee: Gustavo Fernandes Fix For: 9.0.0.Alpha2, 8.2.2.Final, 9.0.0.Final There are two issues when trying to iterate caches configured with compatibility: 1) Since the client-side key tracker calculates segments based on byte[] keys, and the routing on the server is done via Object, there's a mismatch between segments calculated in the server and the client casing NPEs that prevent the data from the socket to be consumed correctly, resulting sometimes in: {code} org.infinispan.client.hotrod.exceptions.InvalidResponseException:: Invalid magic number. Expected 0xa1 and received 0x0 at org.infinispan.client.hotrod.impl.protocol.Codec20.readMagic(Codec20.java:313) at org.infinispan.client.hotrod.impl.protocol.Codec20.readHeader(Codec20.java:115) at org.infinispan.client.hotrod.impl.operations.HotRodOperation.readHeaderAndValidate(HotRodOperation.java:56) at org.infinispan.client.hotrod.impl.operations.IterationEndOperation.execute(IterationEndOperation.java:34) at org.infinispan.client.hotrod.impl.iteration.RemoteCloseableIterator.close(RemoteCloseableIterator.java:64) {code} 2) When the cache configuration has a different name than the cache, CCE errors are thrown: {code} org.infinispan.client.hotrod.exceptions.HotRodClientException: java.lang.ClassCastException: java.lang.Integer cannot be cast to [B at org.infinispan.client.hotrod.impl.protocol.Codec20.checkForErrorsInResponseStatus(Codec20.java:343) ~[infinispan-client-hotrod-9.0.0-SNAPSHOT.jar:9.0.0-SNAPSHOT] {code}
