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