Why do Java people frequently consume exceptions silently?

Because they haven't learned this trick yet:

class ExceptionUtils {
    public static RuntimeException cloak(Throwable t) {
        return ExceptionUtils.castAndRethrow(t);
    }

    @SuppressWarnings("unchecked")
    private static  X castAndRethrow(Throwable t) throws X {
        throw (X) t;
    }
}

class Main {
    public static void main(String[] args) { // Note no "throws" declaration
        try {
            // Do stuff that can throw IOException
        } catch (IOException ex) {
            // Pretend to throw RuntimeException, but really rethrowing the IOException
            throw ExceptionUtils.cloak(ex);
        }
    }
}
