Current Bug #BUG1
Thread1 --> Thread2 --> Thread3
Client1 --> Client2 --> Client3
Server uses threads to distinguish between the clients and fetches their user account based on the associated thread.
So, clients must be executed in chronological manner to support concurrent transactions.
Client2 can only be connected after Client1.
Client3 can only be connectied after Client2.

Future of WLFB bank Application
In future, WLFB will have more than 3 clients.
Probably 10, 20, 30 or more?

Future Updates

1. Update required, to mitigate the bug.
2. Update required, to handle more than 3 clients.
