Lambda-unfriendly method overload
Reports overloaded methods that take functional interfaces with conflicting abstract method signatures.
Such overloads introduce ambiguity and require callers to cast lambdas to a specific type or specify lambda parameter types explicitly. It is preferable to give the overloaded methods different names to eliminate ambiguity.
Example:
Here, Supplier and Callable are functional interfaces whose single abstract methods do not take any parameters and return a non-void value. As a result, the type of the lambda cannot be inferred at the call site unless an explicit cast is used.
