Explanation on practice. If you try to save your object, e.g.:

Set folders = message.getFolders();
   folders.remove(inputFolder);
   folders.add(trashFolder);
   message.setFiles(folders);
MESSAGESDAO.getMessageDAO().save(message);

you don't need to set updated object to a parent object:

message.setFiles(folders);

Simple save your parent object like:

Set folders = message.getFolders();
   folders.remove(inputFolder);
   folders.add(trashFolder);
   // Not set updated object here
MESSAGESDAO.getMessageDAO().save(message);
