Liferay Docker Image 7.4 using JDK8

Issue

• When trying to install docker image for 7.4 u50, it does not allow to change the version to JDK8, it remains on JDK11.

Environment

• Liferay DXP 7.4.

Resolution

• Please be aware that since 7.4 u18 docker images are only using JDK11, so it is not possible to change the version to JDK8.

Additional Information

• Drop JDK8 Support for 7.4 and above docker images
