OpenJDK Server VM warning: No monotonic clock was available - timed services may be adversely affected if the time-of-day clock changes

[juliusjava]

When I run a docker image built from adoptopenjdk:15-jdk-hostspot on my raspberry pi 3B (arm32v7 architecture) and start any java application inside a container, I get the following warning:
OpenJDK Server VM warning: No monotonic clock was available - timed services may be adversely affected if the time-of-day clock changes

At least theses versions are also affected:
14-jdk-hostspot
11-jdk-hostspot

When I execute date inside a container multiple times, it prints the following random dates:
Thu 19 Feb 1970 02:46:19 PM UTC
Thu 19 Feb 1970 11:54:27 PM UTC
Tue 24 Feb 1970 03:22:35 PM UTC
Tue 03 Mar 1970 03:15:07 PM UTC

When I execute "date" directly in my raspberry pi OS, it prints the following correct dates:
Wed 18 Nov 21:17:42 EET 2020
Wed 18 Nov 21:17:43 EET 2020
Wed 18 Nov 21:17:44 EET 2020
Wed 18 Nov 21:17:51 EET 2020

Moreover, my springboot applications inside a container also starts only randomly. Most of the time it simply does not start, only mentioned warning is printed in logs. But the same application starts and operates correctly when I run it directly from raspberry pi OS.

One more thing: when I run for example tomcat:7-jdk8-adoptopenjdk-hotspot image and execute date command, it prints date correctly. Same applies to alpine image. So it shows, that this is not a hardware or raspberry pi OS issue.

Can you please check if you see the same behaviour with a ubuntu:20.04 image ?

I meant to run date on a bare ubuntu:20.04 image to see if it prints random dates. I am suspecting this to be a Ubuntu issue as all the above reported images have that in common.

@aahlenst thanks ! ... That confirms that it is a Ubuntu 20.04 issue.
@juliusjava I think this needs to be reported at the official ubuntu github.

[juliusjava]

Sorry, that I couldn't reply faster.
Thank you all for troubleshooting this issue so fast.
I will try to dig into this with ubuntu guys to this issue tianon/docker-brew-ubuntu-core#196, which I just have created with specific reproduction info.

[juliusjava]

Guy from ubuntu image project helped me and I was able to solve this issue by updating libseccomp librarry on my raspberry (docker host) from ~2.3.2 to 2.5.0.
See more details here tianon/docker-brew-ubuntu-core#196
