Yes, [current master](https://github.com/openjdk/jtharness/commit/b9f4a2c03135208608b7e1a6586be6fe57a062d6) does fix this issue (and sure in a better way):

generate.release.file:
     [echo] Warning: the latest git commit ID could not be determined
     [echo] generated /home/azul/azul/jtreg/make/../build/deps/jtharness/build/binaries/release file:
     [echo] =================================================================
     [echo] JTHARNESS_VERSION=6.0 b24
     [echo] BUILD_DATE=Aug 18, 2022

For b24 it would be nice to also deal with #35 but sure up to you.
