### Which Issue(s) This PR Fixes - Fixes #10831 ### Brief Description `CompactionLog.OffsetMap` previously used `Math.abs(index) % capacity` to select a bucket. For `Integer.MIN_VALUE`, `Math.abs` remains negative and can produce an invalid negative `ByteBuffer` position. Use `Math.floorMod(index, capacity)` so every hash maps to a valid non-negative bucket. A deterministic `MessageDigest` regression test produces `Integer.MIN_VALUE` and verifies both `put` and `get` paths. This follows up on #10841, which was closed without being merged. ### How Did You Test This Change? - `mvn -B -ntp -pl store -am -DskipITs -Dtest=OffsetMapTest -Dsurefire.failIfNoSpecifiedTests=false -Dspotbugs.skip=true test` - `OffsetMapTest`: 3 tests passed - Reactor: 4 modules succeeded - Checkstyle: 0 violations -- This is an automated message from the Apache Git Service.
