[CRIU] CRIU + OpenJDK

[Jonathan Bell]

Hi,
I see via the CRIU wiki that OpenJDK is supported. However, when I try to checkpoint a trivial program running in OpenJDK, I get the following error:
$ sudo criu dump -D checkpoint -t 1188 --shell-job
Error (parasite-syscall.c:387): si_code=4 si_pid=1189 si_status=5
Error (parasite-syscall.c:387): si_code=4 si_pid=1190 si_status=5

Is there any advice as to what may be causing this issue? Is OpenJDK indeed supported by CRIU? I am very interested in checkpointing and restoring a JVM.
