If your locale is non-US, some tests are likely to fail. To work around this you can set the locale to US. On Unix platforms simply setting LANG="en_US" in the environment before running tests should work. On Windows or MacOS, setting JTREG="VM_OPTIONS=-Duser.language=en -Duser.country=US" helps for most, but not all test cases.

However, on MacOS 12.1, even with the above suggestions, some tests still fail, including the following in tier-1. The tests expects output messages in English, but Chinese message are still produced.
