Hi Sato-san,
Thanks for your comment.
I uploaded new webrev:

Hi Suenaga-san,
Thank you for the update. I think your changes to the return values of
MultiByteToWideChar look good.
Then I noticed (should have noticed in the first place, sorry) that the error handling in canonicalize_md.c is
incorrect (unrelated to your change). All error cases "goto finish" which would end up "free(NULL)"
in some cases, e.g., line 340 (in the new file) should not end up calling "free(wresult)" and
"free(wpath)"
java_md.c
- "convert_to_unicode()" has different indentation than others (2 spaces which
should be 4).
I fixed it.
- Should "wpath" be set to NULL before returning EINVAL at line 524? I don't know the
contract of "create_unc_path", but the caller would receive a garbage pointer as a return
value.
create_unc_path() is static function, and it would be called by just JLI_Open().
If create_unc_path() would be failed (it means `err` is set excepting
ERROR_SUCCESS), wpath would call free() when it is not NULL.
Thus we should set related values as below:
A: wpath = NULL, err != ERROR_SUCCESS
B: wpath != NULL (not free'ed), err != ERROR_SUCCESS
I implemented A in this webrev because it is simple.
Thanks,
Yasumasa
Nit: please add "noreg-hard" tag to the JIRA issue.

I forgot to free buffer if MultiByteToWideChar() failed in zip_util.c .

Hi Suenaga-san,
I think the return value from the second MultiByteToWideChar invocation should
be examined (non-zero), and if it was not successful, appropriate action should
be taken.

Hi all,
Please review this change:
JBS: https://bugs.openjdk.java.net/browse/JDK-8240725
webrev: http://cr.openjdk.java.net/~ysuenaga/JDK-8240725/webrev.00/
We found the issue that HotSpot does not start when it is deployed on the path
which contains CJK character(s), and it has been fixed in JDK-8240197.
On the review of JDK-8240197 [1], we concern similar issue might occur in other
place, and I found potentially problem in below:
- ZFILE_Open() @ zip_util.c
- JDK_Canonicalize() @ canonicalize_md.c (for Windows)
- create_unc_path() @ java_md.c (for Windows)
- Platform::MultibyteStringToWideString() @ WindowsPlatform.cpp
This change passed tests on submit repo
(mach5-one-ysuenaga-JDK-8240725-20200309-0811-9304139).
Thanks,
Yasumasa
