  /**
   * While we transition ownership from the Beans API to the Kernel API for core database

   *
   * <p>Users / \ Beans API Cypher \ / Kernel API | Kernel Implementation
   *
   * <p>But our current intermediate architecture looks like this:
   *
   * <p>Users / \ Beans API <--- Cypher | \ / | Kernel API | | Kernel Implementation
   *
   * <p>Meaning Kernel API and Beans API both manipulate the underlying kernel, causing lots of
   * corner cases. Most notably, those corner cases are related to Transactions, and the interplay
   * between three transaction APIs: - The Beans API - The JTA Transaction Manager API - The Kernel
   * TransactionContext API
   *
   * <p>In the long term, the goal is for JTA compliant stuff to live outside of the kernel, as an
   * addon. The Kernel API will rule supreme over the land of transactions. We are a long way away
   * from there, however, so as a first intermediary step, the JTA transaction manager rules
   * supreme, and the Kernel API piggybacks on it.
