I look at this new exception class and discuss advantages of using it in this blog post and compare it to Java 7’s more general approach for handling multiple exceptions in a single catch clause.

Having multiple occurrences of a 200 line code block in catch clauses sets off a red flag, but regardless, it's better to factor out that code than to duplicate it.

For these reasons, Java requires your try blocks to actually throw the exceptions that their catch clauses catch.
