RFR: 8365398: TEST_BUG: java/rmi/transport/checkLeaseInfoLeak/CheckLeaseLeak.java failing intermittently

[Johny Jose]

Increasing the count value of available objects to 6 (which is half the number of objects created). The failures were reported in macos which seems to take more time to clear the objects. Though majority runs has less values for objects (less than 4), in order to eliminate intermittent failures, raising the threshold values to 6
