Bug#834913: libslf4j-java: FTBFS too much often (failing tests)

Sat Aug 20 15:18:19 UTC 2016

Package: src:libslf4j-java
Version: 1.7.21-1
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
doing "dpkg-buildpackage -A" does not mean anything special.

I attach three different failed builf logs.

Thanks.
