Bug#834671: libxalan2-java: FTBFS in testing (Error: could not match input)

[Santiago Vila]

Package: src:libxalan2-java
Version: 2.7.1-9
Severity: serious

Dear maintainer:

I tried to build this package with "dpkg-buildpackage -A"
(which is what the "Arch: all" autobuilder would do to build it)
but it failed:

--------------------------------------------------------------------------------

Because this source package only generates "Arch: all" packages, this
is the same as a FTBFS bug in the usual sense and the fact that I was
using "dpkg-buildpackage -A" is quite irrelevant.

For this particular package, I've also checked that it fails to build
from source in the reproducible builds site:

Thanks.

Dear Debian Java Maintainers:

Thank you for fixing this bug.

I have a question: Is there a particular reason why you are still not
doing source-only uploads?

Source-only uploads are particularly interesting for "Arch: all"
packages, because it's a way to double-check for package correctness
(FTBFS bugs in particular).

Ordinary uploads for "Arch: any" are tested by all the arch-dependent
autobuilders, so the effect of not doing source-only uploads in "Arch: all"
packages is that they are tested a lot less than "Arch: any" packages.

Thanks.
