      JDK-8300208 (Optimize Adler32 stub for AVX-512 targets) seems to change the behaviour of adler32.

      The attached repro shows that the adler32 checksum for the attached data file changes after the loop is optimized.

      $ java AdlerTest
      failed iteration: 5413 - expected 1265275828, actual 14717876

      The data was generated with `head -c 72188 /dev/random`
