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.

I have updated the summary of this PR.

This does work for this test and tests that fail before.
However, this will make some other tests fail, e.g.

test/hotspot/jtreg/compiler/jvmci/TestInvalidJVMCIOption.java

`JAVA_TOOL_OPTIONS` will produce a message in stderr, it seems there is no way to suppress it.
