Answer 1

As you see the exception it clearly mentions following error
Comparison method violates its general contract!
This is due to Comparator is not transitive, There is ID Comparator and the ids in database are randomly generated, so randomly generated ids making problem to this comparator
"Comparison method violates its general contract!"
conclusion : Randomly generated ids have to be in incremented way, should not contain negative values
