 * Thread safety: it is possible for the same instance of this class to be used by multiple caches at the same time e.g.
 * when the same instance is passed to multiple configurations.
 * As infinispan supports parallel test startup, it might be possible for multiple threads to invoke the
 * getTransactionManager() method concurrently, so it is highly recommended for instances of this class to be thread safe.
