Rule Definition
Care must be taken if completion of a try-catch block occurs as a result of executing a return. If a finally block also returns a value, then that return supersedes any previous return in the try-catch block. Also, if an exception was thrown in the try or catch blocks that was not caught, then the execution of a return in the finally block prevents the exception from being thrown to the caller (because it is not possible for the caller to simultaneously evaluate the return and catch the exception).
