Caused by: java.io.IOException: The property has a getter "public java.lang.Boolean org.infinispan.config.Configuration$TransactionType.isAutoCommit()" but no setter. For unmarshalling, please define setters. (Or if this is a collection property, make sure that the getter returns a collection instance.)
