[jdk17u-dev] RFR: 8318410: jdk/java/lang/instrument/BootClassPath/BootClassPathTest.sh fails on Japanese Windows

[Kimura Yukihiro]

I would like to fix this issue because the test dose not work as intended.
8318410 resolved two issues. However, the first issue related to JEP400 is not relevant to JDK17.
Therefore, I would like to backport only the second issue,
which is the problem of tests not running properly on Windows cygwin.

Could someone please review it?

Thanks,
Kimura Yukihiro
