As part of the wildfly-naming-client integration work, we need to upgrade to JBoss Marshalling 2.0.0.Beta3 (see
WFCORE-2044 and WFLY-7675). This upgrade currently results in testsuite failures in org.jboss.as.test.clustering.cluster.sso.ClusteredSingleSignOnTestCase since Infinispan is still on JBoss Marshalling 1.4.x. ISPN-3391 was created a while back to upgrade Infinispan to JBoss Marshalling 2.0.0 but it seems this issue was waiting on a JBoss Marshalling release that adds back some classes that had previously been removed. JBoss Marshalling 2.0.0.Beta3 contains these classes so it should be possible now to upgrade Infinispan to this new version.
