Answer
Misusing singleton scope for stateful beans.
Singleton scope is the default and often misused for beans that need to maintain a user-specific state, leading to incorrect data being shared across users. For example, if a ShoppingCart bean is singleton, all users would share the same cart, which is not the desired behavior. Instead, a session scope should be used.
