The rolling upgrade procedure for the REST client migrates data from a previous version of JBoss Data Grid server ("source") to a new version ("target"). The rest-store configuration element is required for this procedure to succeed. However, it is not possible to successfully start the "target" node with rest-store element defined. The server fails to start with java.lang.ClassNotFoundException: org.apache.commons.codec.EncoderException

As a result, it is not possible to perform rolling upgrades with REST client from JBoss Data Grid 6.1.0.GA to JBoss Data Grid 6.2.0.Beta.

Found in DR4 as the first release which contains Infinispan 6.0.0.Aplha4 and therefore REST Cache Store + possibility of REST Rolling Upgrades.
I've experienced problems with starting JDG node using standalone-rest-rolling-upgrade.xml example configuration (for target node).
Please see report in attachment.
You can find 2 console outputs of jdg server. The second one is after some changes in modules.xml (in rest cachestore module).
Details are shown and described in that file.
