  • Field Details

    • LOG

      protected static final EnginePersistenceLogger LOG

    • MAX_EXCEPTION_MESSAGE_LENGTH

      public static final int MAX_EXCEPTION_MESSAGE_LENGTH
      Note: String.length() counts Unicode supplementary characters twice, so for a String consisting only of those, the limit is effectively MAX_EXCEPTION_MESSAGE_LENGTH / 2
