Rule S2221: "Exception" should not be caught when not required by called methods

RSPEC-2221

Catching Exception seems like an efficient way to handle multiple possible exceptions. Unfortunately, it traps all exception types, both checked and runtime exceptions, thereby casting too broad a net. Indeed, was it really the intention of developers to also catch runtime exceptions? To prevent any misunderstanding, if both checked and runtime exceptions are really expected to be caught, they should be explicitly listed in the catch clause.
