This pull request is focused on resolving occurrences of Sonar rule squid:S1155 - Collection.isEmpty() should be used to test for emptiness.
Using Collection.size() to test for emptiness works, but using Collection.isEmpty() makes the code more readable and can be more performant. The time complexity of any isEmpty() method implementation should be O(1) whereas some implementations of size() can be O(n).

Please let me know if you have any questions.
