Bug#927244: mina: FTBFS (Unknown option: source 1.7 -target 1.7)

[Santiago Vila]

Package: src:mina
Version: 1.1.7.dfsg-12
Severity: serious
Tags: ftbfs

Dear maintainer:

I tried to build this package in buster but it failed:

--------------------------------------------------------------------------------
[...]
 debian/rules build-indep
dh build-indep --with javahelper
   dh_update_autotools_config -i
   dh_autoreconf -i
   jh_linkjars -i

Unknown option: source 1.7 -target 1.7
jh_build: unknown option or error during option parsing; aborting

make: *** [debian/rules:39: build-indep] Error 2
dpkg-buildpackage: error: debian/rules build-indep subprocess returned exit status 2
--------------------------------------------------------------------------------

The build was made in my autobuilder with "dpkg-buildpackage -A"
and it also fails here:

https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/mina.html

If this is really a bug in one of the build-depends, please use reassign and affects,
so that this is still visible in the BTS web page for this package.

Thanks.
