Start with MacPathTest.java and UnicodeTest.java, then inspect the reported failures at MacPath.java:146 and UnicodeTest.java:75, including TestHelper.java:278 for the compilation error. Reproduce the tests on macOS 10.14 and macOS 12 and determine what differs; done means both tests pass on the affected macOS environment without regressing the passing environment.
