Hi, I continue experimenting with building mainline on Nix and I've made some progress. Capstone, Ant and others are in, but I had to work around an issue when trying to run JMH benchmarks [1].
Seems like when `test` make target is run, `jrt-fs` jar file is created passing in `--date ...`. In Nix, I was getting this error: ``` /nix/store/5y040sypyg0amh0igxs9rnx5fmj0d88i-temurin-bin-23.0.2/bin/jar --create --date 1980-01-01T00:00:00Z --file /Users/galder/1/jdk-avoid-cmov-long-min-max/build/release-darwin-arm64/support/modules_libs/java.base/jrt-fs.jar --manifest /Users/galder/1/jdk-avoid-cmov-long-min-max/build/release-darwin-arm64/support/modules_libs/java.base/_the.jrt-fs.jar_manifest ... date 1980-01-01T00:00:00Z is not within the valid range 1980-01-01T00:00:02Z to 2099-12-31T23:59:59Z ``` @Andrew Leonard <anleo...@redhat.com> found the root of this validation in [2]. It seems unlikely this is going to change. The cause is that on Nix shell envs `$SOURCE_DATE_EPOCH` is set to 315532800 which is 1980-01-01T00:00:00Z. This can be easily worked around by unsetting SOURCE_DATE_EPOCH and that works fine for my use case. However, @Thomas Fitzsimmons <fitz...@redhat.com> had a very good point to make: > I also wonder why the test harness is passing --date $SOURCE_DATE_EPOCH, since the test jars are not distributed, not sure why they'd need to be reproducible... I think his question is valid. Why pass --date for a test jar?
