The only thing that I think if slightly leaky is updating an existing entity.
It isn't the only leak you have:
public interface ISession : IDisposable
This is a leaky abstraction. You have a specific implementation in mind - one that implements IDisposable, and you're leaking this specifi...

I am wondering what a better solution would be for this bit of code:

A couple of hours ago I asked a question on Stackoverflow to find out if there is a good way to delete files in a folder only if all files are indeed deletable and I got some good answers that led me (I think) in the right direction
Based on the two currently most upvoted answers I scrambled tog...

The first piece of code should cover the standard expected data. But as you can easily see, the data not always conveys to this standard. The code works great but I wonder if this is thought be a miss-use of the try/except clause. Better to go with if/else?

Why not use a class to hold both the file and the lock, so you don`t need to manage two Lists like:
public class SafeDirectory {
private File directory = null;
private FileLock lock = null;
private List<SafeFile> deleteableSafeFiles = new ArrayList<>();
public SafeDirectory(Str...
Without any more information than in your question, this is just a thought. I have no idea what Sonar would say about this approach:

Instead of two for loops and checking the names chars with each char of VALID_CHARS i used one for..loop and check validness by checking, if the name contains the char by using the String.indexOf() method.

I recently came across code that looked something like this (generates 4 random numbers in an array, this is not the actual code, I just wrote this up now, so it's untested):
var uniqueNumbers = new Array();
var count = 4;
var max = 10;
function main() {
for (var i = 0; i < count; i++) {

You don't need invalidchoice() as it just prints a statement and nothing else. Just put the printf() under default.
Consider receiving all user input in main() and having the functions only do the calculations. It's best to have a function do one (useful) thing.
In this form, the functions co...
It depends on the proportions of count and max, obviously, but most importantly on the behaviour of the random number generator. ECMAScript leaves the behaviour of random() to the implementation, so there's no immediate answer; it would be platform dependent.
