Next layer faills too, doe's not it ? If you will handle MyExeption this
way in next layer you will log it twice and
It will dublicate code. I think It is better log all fatal exeptions in
single place, I prefer this way :
void register(MyObject value){
Connection connection = getConnection();
updateOrInsert(connection,value);
log.info(" registred " + value.getId() );
}
The last layer ( resource management ) logs all unhandled exeptions and
releases resources.
