This is probably a useless me-too. Sorry if so, but there aren't any yet, so it might look like it's only the OP. It's not. I saw the same on two machines today, the smaller upgrade being from 7u121-2.6.8-2~deb8u1 to 7u131-2.6.9-2~deb8u1. My attention was drawn to the system by the impressive number of minutes it was taking to install something that normally only takes a handful of seconds. strace on the dpkg process at the top of top(1) revealed where it was in the tree. Ah, I think I see the fix on the way, from http://metadata.ftp-master.debian.org/changelogs/main/o/openjdk-7/openjdk-7_7u131-2.6.9-3_changelog:
openjdk-7 (7u131-2.6.9-3) experimental; urgency=medium * Only include the failing tests in the packages, not the whole test world. * openjdk-7-jdk: Provide openjdk-7-jdk-headless. -- Matthias Klose <d...@ubuntu.com> Sat, 20 May 2017 15:52:17 -0700 Thanks!
