Bodgitt & Scarper 2.2.3 (Locking & Unlocking)

I have used conventional Synchronization technique for my locking in my assignment. I used Roberto's tool for verifying my locking and it is running normally but with RecordNotFoundException . I think this behaviour is normal and expected

Does it mean my locking strategy work fine? My requirement says

Any attempt to lock a resource that is already locked should cause the current thread to give up the CPU, consuming no CPU cycles until the desired resource becomes available.

To meet this requirement, I use wait() in lock method and also use notifyAll in unlock method. Does it sound good ? or Am I doing something different? Is there any solution to verify the above requirement?

PS: Thanks to Roberto's for his tool. It's

Howdy, Sat!

It looks like everything's fine, champion. Just remember that the locking mechanism must work in standalone mode and in networked mode.

You are very welcome, my friend!
