Yes: 
- https://github.com/hibernate/hibernate-orm/blob/master/hibernate-infinispan/src/main/java/org/hibernate/cache/infinispan/tm/HibernateTransactionManagerLookup.java
- https://github.com/jbossas/jboss-as/blob/master/clustering/infinispan/src/main/java/org/jboss/as/clustering/infinispan/TransactionManagerProvider.java
