Removing RecordNotFoundException from subclass

[Jonathan Elkharrat]

i think the RecordNotFoundException in the writing methods is not necessary and here's why:

since the lock method already check that the record exist, and the writing methods
make sure the record is locked, that mean one thing ---> the record exist!

just making a point..

But you are not the first one, that point is already made several times (I made the same remark more than 2 years ago, and not onlt for the write methods, but also for unlock-method )

[Jonathan Elkharrat]

now that you mention it, it's quite contradictory to have a RecordNotFoundException in the unlock method.
suppose someone lock a record, delete it and then call the unlock.
i just found a bug in my code now thanks to you
