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.
