MartijnVisser opened a new pull request, #29515:
URL: https://github.com/apache/flink/pull/29515
## What is the purpose of the change
Replaces the open Dependabot PRs for lz4-java. Supersedes #28820 and #29440,
which both miss the flink-dist NOTICE.
## Brief change log
- lz4-java 1.12.0 and the flink-dist NOTICE
Dependabot proposes 1.11.4, which has the same CVE fixes. This takes 1.12.0
because the lz4-java maintainer recommends it, and its changes are limited to
`LZ4BlockInputStream`, `LZ4FrameInputStream` and `LZ4DecompressorWithLength`,
none of which Flink uses.
## Verifying this change
This change is already covered by existing tests: the compression, hash
table and sorter tests in flink-runtime and flink-table-runtime pass, and the
license checker passes for flink-dist. Round-trip throughput of 32 KiB blocks
through `Lz4BlockCompressor`/`Lz4BlockDecompressor` on the JNI path is within
noise between 1.10.3 and 1.12.0.
