Thank you very much for your reply, Andrea. Yes, this is a really bad
problem that should be fixed, mainly because this kind of problem is not
like a "common bug", or a "little mistake". It is a kind of bug that can
make something completely unreliable. I do not rely on ADB, and I will never
use it until they fix the problem. And I will recommend everybody to not use
ADB as well. I simply do not rely on ADB anymore. That´s sad.
Fortunately, using a XML Beans webservice this problem doesn´t happen. Well,
at least until now this didn´t happen to me.

The attached patch is sub-optimal. In AXIS2-3765 (wasn't aware that it is
the same bug when i created the issue since we only have one byte[]) i
proposed a patch which does not need the extra loop.
Nevertheless it works both ways..
I also patched it locally and we are going live with this patch, even
though i am not really happy about this.

Have you submitted this patch? Is this the same patch that is attached to
JIRA issue AXIS2-3538?
Thanks

In our organisation we wrote a patch, recompiled axis2, and we are using
the patch (with success). I can send the patch to anyone interested, but
I think this is a REALLY BAD problem and should be fixed as soon as

Is anyone in the axis2 team listening?

Alas, I think this is a well-known issue:
https://issues.apache.org/jira/browse/AXIS2-3538
I had an exchange of e-mails with Deepal, but it ended in nothing.
The issue was submitted on 24/Feb/08 09:13 AM and a suggestion for a
patch is available from June 2008, but it is currently unassigned. It is
marked as "critical".
In our organisation we wrote a patch, recompiled axis2, and we are using

but I think this is a REALLY BAD problem and should be fixed as soon as
possible by the axis2 development team.
