Hi Rafael,

I cloned the latest (?) sources from git://git.apache.org/qpid-proton.git in 
order to test your fix.

In the proton-j package I am missing however the following:

import org.apache.qpid.proton.message.MessageFactory;
import org.apache.qpid.proton.message.impl.MessageFactoryImpl;

Did I download the right sources at the right place? Or did the method to 
create Messages change?

Thanks a lot and
Kind regards
Frank

Hi,

I think it's actually a bug that we are overflowing that buffer regardless of 
its size. I've filed a jira for this (
https://issues.apache.org/jira/browse/PROTON-714) and committed what I believe 
is a fix for this. Would it be possibly for you to check whether this does in 
fact solve the problem for you?
