One of our users reported problems when calling Spring's integration in sync mode with transactions and a Cache Store (see the forum reference).

Spring's sync mode invokes computeIfAbsent() method, which in consequence invokes PersistenceManagerImpl. The PersistenceManagerImpl class calls TxBatchUpdater#visitComputeIfAbsentCommand which is not overridden from the AbstractVisitor class. I believe TxBatchUpdater should provide similar #visitComputeIfAbsentCommand implementation to #visitPutKeyValueCommand method.
