12  * A TransactionError indicates that the current transaction has to abort no
13  * matter what. (For example because a dead-lock has been detected.) Therefore
14  * it is an Error instead of an Exception. So it will not be catched by a
15  * "catch (Exception e)" clause, which is the common way to catch exceptions in
16  * the ozone code.
