>
> When an entry is read (1) inside a transaction and then updated (2), there is 
> a chance that concurrent transaction will modify that entry in between (1) 
> and (2). In this case an error is thrown from the first transaction when 
> action (2) is performed and transaction is marked as "rollback only". User 
> need to re-try the whole transaction in this case.
> When native APi is used, then {{CacheException}} is thrown with special 
> message {{Cannot serialize transaction due to write conflict (transaction is 
> marked for rollback)}}. This will be changed in future (AI 2.8|) - special 
> exception type will be thrown.
> When JDBC or ODBC are used, then special SQLSTATE code 40001 (aka 
> "Serialization failure") is propagated to user.
