Found this issue while working through the chapter this morning. The problem was resolved for me by making sure I was using Java 8, not 11, during the build.

Although the use of Java 8 is mentioned at the beginning of the book, reiterating its use in the README files for all the labs might be a good idea, as at the end of 2021 and beginning of 2022, a lot of people might be switching between Java versions quite often.
