/**
* Factory interface, allows {@link org.infinispan.Cache} to use different transactional systems. Names of implementors of
* this class can be configured using {@link Configuration#setTransactionManagerLookupClass}.
* 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:
* {@link org.infinispan.configuration.cache.TransactionConfigurationBuilder#transactionManagerLookup(TransactionManagerLookup)}.
* 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.
