4.0.0-beta images are failing due to wrong JDK version

[rot9mu]

Proposal

At the docker image the JAVA_VERSION=jdk-11.0.24+8 is used. But wiremock has been compiled with a newer version (min. Java 17), so the image is failng with this error: java.lang.UnsupportedClassVersionError

Reproduction steps

Running the doker image failes with following error:

docker run -it --rm -p 8080:8080 --name wiremock wiremock/wiremock:4x-beta
Unable to find image 'wiremock/wiremock:4x-beta' locally

Status: Downloaded newer image for wiremock/wiremock:4x-beta

java.lang.UnsupportedClassVersionError: wiremock/Run has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 55.0

Hi,

Any chance to solve this please?
It happens for me on deploying it on OpenShift 3.

Thx

This should be fixed now @latannon. Are you certain you don't have an old cached version?
