Elasticsearch images failing for some versions, causing failure for integration tests.

[convenient]

I have traced this issue to the source here wardenenv/images#86.

Some versions of elasticsearch are failing to boot with

2026-02-17 09:07:21,994 main ERROR Could not reconfigure JMX java.lang.NullPointerException: Cannot invoke "jdk.internal.platform.CgroupInfo.getMountPoint()" because "anyController" is null
Exception in thread "main" java.lang.NullPointerException: Cannot invoke "jdk.internal.platform.CgroupInfo.getMountPoint()" because "anyController" is null
	at java.base/jdk.internal.platform.cgroupv2.CgroupV2Subsystem.getInstance(CgroupV2Subsystem.java:81)

Raising here for visibility, for anyone else seeing that their tests were failing.

So i was debugging this last week @sprankhub, I think I narrowed it down to not specifically the warden docker images but rather the images and the combination of the docker version used in the github action.

I could see the github action broke on a newer version of docker

See that when it failed it was on 1.52 last week

When I went today to try and re-test, potentially forcing old versions of ubuntu or docker it was working and the github action docker version had reverted to the older working version
