@ferenc-csaky Our Java applications (high throughput) run with Java 11 /21 are using `-Dio.netty.tryReflectionSetAccessible=true` when we upgrade From Java 8, this is really needed to avoid OOM and reduce GC pressure, the old one does not need it because it's Unpooled, which generates much more gc counts and hurt performance. I vote for adding this by default or adding the `-Dio.netty.tryReflectionSetAccessible=true` to the release notes, people who want the old behavior can enable it with `-Dio.netty.allocator.type=unpooled` if they like more gc. -- This is an automated message from the Apache Git Service.
