Description

Nightly build for branch-2.2 is using JDK11 accidentally. Yetus tries to set JAVA_HOME to JDK8 but the path does not exist and it falls back to JDK11.

[2021-01-07T19:11:14.729Z] WARNING: JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64 does not exist. Dockermode: attempting to switch to another.
[2021-01-07T19:11:14.729Z] WARNING: Setting /usr/lib/jvm/java-11-openjdk-amd64 as the JAVA_HOME. 

With JDK11 there are a lot of compilation errors.
