Why
when we have 2 concurrent requests 1 and 2,
#1
goes intofinally
block and removes Sema instance and then#2
goes intofinally
block and tries to release released Sema instance but that instance was removed by#1
What
Checks whether lock exists in the hashmap of locks because it could be released and cleared by another validation request
