Bug#927016: libnanoxml2-java: FTBFS (Unknown option: source 1.8 -nowarn)

[Santiago Vila]

Package: src:libnanoxml2-java
Version: 2.2.3.dfsg-6
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
   debian/rules override_dh_auto_build
make[1]: Entering directory '/<<PKGBUILDDIR>>'
jh_build -o'-source 1.8 -nowarn' -N nanoxml-lite.jar Sources/Lite/
jh_build: Use of -N as --no-javadoc is deprecated as it clashes with debhelper's -N option
jh_build: Please migrate to --no-javadoc as soon as possible
jh_build: If you wanted debhelper's --no-package option, then please use -N<pkg> (without a space)
Unknown option: source 1.8 -nowarn
jh_build: unknown option or error during option parsing; aborting
make[1]: *** [debian/rules:23: override_dh_auto_build] Error 25
make[1]: Leaving directory '/<<PKGBUILDDIR>>'
make: *** [debian/rules:20: 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/libnanoxml2-java.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.
