QuickstartIT.java test works with Oracle JDK but not with Open JDK

In which file did you encounter the issue?

java-docs-samples/firestore/src/test/java/com/example/firestore/QuickstartIT.java

Describe the issue

The build step (mvn clean package) works if Oracle JDK is installed (I had Java(TM) SE Runtime Environment (build 1.8.0_191-b12)). If the OpenJDK is used and the Oracle JDK is not installed, it fails to build (but works if the Oracle JDK is at least installed).
The build succeeds if the QuickstartIT.java file is removed.
