You can also rethrow checked exceptions as runtime exceptions by exploiting type erasure:

    public static RuntimeException unchecked(Exception e) {
        Exceptions.<RuntimeException>throw_checked(e); 
        return null; 
    }
    private static <E extends Exception> void throw_checked(Exception e) throws E {
        throw (E) e;
    }

then you can do this:

    try { ...
    } catch (IOException e) {
        throw unchecked(e);
    }

And the original exception is thrown without being wrapped. It's as though you had `throws IOException` on your method signature.

This is from my original solution to the problem: https://github.com/rogerkeays/jamaica-core/blob/0cc98b114998...
