Issue build tests-all

[Johnson, Andy]

I discovered that jdk-9 is needed to build tests-custom.  Now that I have successfully build and run tests-custom, I am trying to build tests-all.  When it gets up to tests-chapter-1b, the build fails with compile-time errors like the following:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.5.1:compile (default-compile) on project jcstress-tests-chapter-1b: Compilation failure: Compilation failure:

And many more such errors.  I have successfully built tests-all in the past.  Does anyone have any idea what recent change might have caused these build failures?
