Hi!
I am planning to do GSoC and I would like to work on the serializers. More
specifically I would like to implement code generation. I am planning to
send the first draft of the proposal to the mailing list early next week.
If everything is going well, that will include some preliminary benchmar
Hi,I did not want to send this proposal out before the I have some initial
benchmarks, but this issue was mentioned on the mailing list (

Hi!
As far as I can see the formatting was not correct in my previous mail. A
better formatted version is available here:

Sorry for that.

Hi,
I have updated this draft to include preliminary benchmarks, mentioned the
interaction of annotations with savepoints, extended it with a timeline,
and some notes about scala case classes.

Hi,
The GSoC project proposal was accepted! Thank you for all your support. I
will do my best to live up to the challenges and deliver everything that
way planned for this summer.
Best Regards,

Hi!
I have created a proof of concept implementation of my GSoC project [1]:
introducing code generation to the serializers. The code is available here
[2]. Unfortunately I have run into a problem that I am unable to debug. I
generated some code that I compiled using the Janino compiler [4]. I did

you see similar phenomenon? What would be the best way to debug this?
I have attached the generated Java code.
Thanks in advance,
Gábor

Hi!
While I was working on code generation support for PojoComparators, I
stumbled upon the compareSerialized method [1]. It first creates two new
instances and then it is using the reusing overloads of the serializer.
Calling the non-reusing overload would create the instance anyways. Is
there a
