[CRIU] checkpoint/restore full-fledged java applications

[Zuocheng Ren]

Hi all,
I notice that in http://criu.org/What_software_is_supported, java is
said to be partially supported. In one of my project, I need to use
CRIU to checkpoint/restore full-fledged java applications which may
have open sockets, open files, and etc. I'm wondering what's missing
(if there is any at all) in the current CRIU/kernel implementation to
make this possible? If there is anything that needs to be done, I'm
happy to contribute on this aspect. Right now, I'm encountering some
errors when restoring java applications. The error messages include
"Can't open file /tmp/hsperfdata_<username>/<pid>", and "Thread pid
mismatch". Any ideas of how to troubleshoot these issues? Thank you!
