Re: (java) Builds not reproducible on armhf

[Mechtilde Stehmann <mechtilde@debian.org>]

Hello,

in the meantime I did some more tests to find the reason for it.

I build it again with pbuilder specifying ARCH=armhf and get the right 
date for the pom file (same date as the amd64 build)

Now I think I need access to an armhf box to test it natively.

What should I do to get temporary.

Kind regards

Mechtilde
