Description Bernhard Wiedemann 2024-03-11 08:38:07 UTC

Created attachment 873384 [details]
diff from build-compare

While working on reproducible builds for openSUSE, I found that
our java-21-openjdk binaries vary between 1-core and 4-core builds.

https://rb.zq1.de/compare.factory-20240228/diffs/java-21-openjdk-compare.out
has the diff (also attached)

There may be additional issues from ASLR that I am still investigating.

I patched the timestamp in the jlink tool that generates the JMOD packages. Let us see whether it makes the "modules" diff smaller.
