Bug#849217: jruby: FTBFS (sbuild hangs)

[Santiago Vila]

Package: src:jruby
Version: 1.7.26-1
Severity: serious

Dear maintainer:

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

E: Build killed with signal TERM after 60 minutes of inactivity
--------------------------------------------------------------------------------

In this case, sbuild aborted the build because it detected too much
time without log activity, which is what happens when the build hangs.

If you need a full build log, just say so and I will include it,
but the build also hangs in the reproducible builds autobuilders:

https://tests.reproducible-builds.org/debian/rb-pkg/unstable/amd64/jruby.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 page for this package.

Thanks.
