Hi Severin!

It doesn't get that far, unfortunately:

(sid_armel-dchroot)glaubitz at abel:~/openjdk/hs$ /home/glaubitz/openjdk/hs/build/linux-arm-normal-zero-release/jdk/bin/java -Xlog:os+container=debug
Segmentation fault

I don't have access to these (it's one of Debian's porterboxes):

(sid_armel-dchroot)glaubitz at abel:~/openjdk/hs$ /proc/self/mountinfo
-bash: /proc/self/mountinfo: Permission denied
(sid_armel-dchroot)glaubitz at abel:~/openjdk/hs$ /proc/self/cgroup
-bash: /proc/self/cgroup: Permission denied
(sid_armel-dchroot)glaubitz at abel:~/openjdk/hs$

Would that cause the problem?
