Dump and restore a JVM X11 AWT application with CRIU on Linux
Hi, friend. You can reach me at [email protected] or +358405168122.
I'm a backend developer and architect working on modern stuff, mostly in the media and comms industries, since the late 90s.
These are some of the hobby projects I've worked on over the years, in order to scratch an itch, or learn about one technology or another. Work stuff goes on a different account.

Solution, make sure that your process STDIN, STDOUT and STDERR are all pointing to files or devices which CRIU can handle, and which will still be around.

This is apparently just an issue in the CRIU TID printing code, since using CRIT to look at the full TID list (crit show pstree.img) and pushing the ns_last_pid past that list and then attempting a restore will work.
