Infinispan cache inaccessible after restart of application server

Issue

• Running JBoss EAP 6.2 CP03 with a modeshape module (3.8) with infinispan as cache. We had a similar set-up in EAP 6.1 with modeshape 3.7.4 which worked fine. In EAP 6.2 CP03 everything runs fine until we restart the app server. After the restart modeshape/infinispan is not accessible any-more. This is the error we get after the restart :
