[jdk17u-dev] RFR: 8313815: The exception messages printed by jcmd ManagementAgent.start are corrupted on Japanese Windows

[Kimura Yukihiro]

I would like to fix this issue 
because users can not read the exception message of jcmd ManagementAgent on localized Windows platform and can not understand what happened.
Testing:
  all serviceability area tests jdk_svc, and a specific test to verify the fix.

Could anyone review the fix please?

Thanks,
Kimura Yukihiro
