This commit resolves a Netty version conflict that was causing the warning: "NoClassDefFoundError: io/netty/util/internal/ClassInitializerUtil" The issue was caused by multiple Netty versions in the dependency tree: - Datastax Cassandra driver (3.11.3) brought in Netty 4.1.77.Final - grpc-netty (1.35.0) brought in Netty 4.1.52.Final This conflict prevented Netty from loading its native epoll transport, causing it to fall back to NIO with a warning message. Solution: - Upgraded o11yphant from 1.9.1 to 1.9.2 - Version 1.9.2 removed the grpc-netty dependency from o11yphant-trace-otel - Removed direct grpc-netty dependency from embedder module This is a cleaner solution than forcing Netty version alignment via BOM, as it eliminates the conflicting dependency entirely. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
