Hi,

this code works as expected:

class RetryException < RuntimeError; end;

class Something
def do_something
    @i = 3
    begin
        get_data(@i)
    rescue RetryException => detail
        p "Retry exceptionxxxx"
        @i += 1
        retry if detail.ok_to_try
    rescue
        p $!
    end
end

def get_data(local_i)
    local_i.upto(10) do|t_i|
        if t_i == 5
            raise RetryException.new(true),"Retry exception"
        end
        p t_i
    end
end
end


However, if i change second method:

begin
        timeout(6) do
            ret_data = @proxy_con.gets()
        end
        second_part = ret_data.split('##')[1].split(',')
        last_part = second_part[-1]
        ret_echo_id = last_part.split('=')[1]
        #ret_echo_id = "foobar"
        second_part.delete_at(-1)
        second_part = second_part.join(',')
        p ret_echo_id

        if @v_echo_id != ret_echo_id
            raise RetryException #line 94
        end

        first_part = ret_data.split('##')[0]
        ret_data = first_part + "##" + second_part +"##"
    rescue Timeout::Error
        raise "Timeout Error"
    rescue
        raise "Some other error"
    end

In this case, when the exception is raised on line # 94, then in the calling
method...it is handled as general rescue...and its not handled as Exception
of Class RetryException.However, if i remove the last rescue statement in
the second method it works alright.

The Road goes ever on and on
Down from the door where it began.
Now far ahead the Road has gone,
And I must follow, if I can,
Pursuing it with eager feet,
Until it joins some larger way
Where many paths and errands meet.
And whither then? I cannot say.
