The static analysis tool found a possible resource leak, which I am not sure if it is a false positive or not:
102 Statement stmt = idleConnections.getFirst().getConnection().createStatement();
(Variable "stmt" going out of scope leaks the resource it refers to. )
I could not find any piece of code, that would close this resource.
The Statement close() method docs tells us, that it is only a good practice to close the resource manually, with, in this case, stmt.close().
Can you please check, if this finding is reasonable, or not?
