Periodic jextract failure on Windows

[Duncan Gittins]

Some feedback on jextract - I'm using Windows OpenJDK 64-Bit Server VM
(build 18+36-2087) and a recent build of jextract from Apr 15 (commit
c1b0e7ec4c4c635f26ef19dbc5f3f3acc2b9f7ee) just after the Windows gradle
build was fixed.

Occasionally jextract fails on Windows, and gives simple message: "Child
process exited with code xxxxxx". A re-run of same command works. I've seen
this issue a few times in the last year on earlier JDK+jextract so the
issue isn't specific to the above JDK+jextract combination.

It does not make a difference which of my input configurations I use, but
see contents of the @argfiles used below which caused the recent error
message:

    > %JEXTRACT% @headers\C.conf @headers\C.sym
    WARNING: Using incubator modules: jdk.incubator.foreign
    Child process exited with code 3221225477

    >%JEXTRACT% @headers\C.conf @headers\C.sym
    WARNING: Using incubator modules: jdk.incubator.foreign

I've no reason to suspect my PC disk is beginning to fail which might be an
explanation. Any suggestions?

Kind regards
