Issue with ibmcom/websphere-liberty:20.0.0.9-full-java8-ibmjava-ubi since latest update of Java

[gillesde]

We are building our images based on your ibmcom/websphere-liberty:20.0.0.9-full-java8-ibmjava-ubi for a while now with some success.

However, suddenly, we are getting issues and segmentation fault on a Ant task. There was a change pushed few days ago which seems to correspond to the start of our problems. As the image is referenced by a tag, we can't select the previous version..

Nothing changed on Liberty, but the base IBM Java image changed from 1.8.0_sr6fp16 to 1.8.0_sr6fp20: https://github.com/ibmruntimes/ci.docker/blob/master/ibmjava/8/jre/ubi/Dockerfile

Our issue looks like the following:

This repo is for docker issues, not JVM issues. Is it possible to raise this problem via IBM support? The diagnostic files produced by the crash are needed in order to pursue it (system core, javacore, etc). If you want to pursue it via open source channels, you can open the issue at https://github.com/eclipse/openj9/issues/new?labels=userRaised&template=user-problem.md and pls provide the diagnostic files via a file sharing service.
