Jan 1, 2024In 2024-01, OpenLiberty/open-liberty delivered two major Netty-based transport enhancements that improve reliability, security, and scalability of WebSocket and HTTP transport layers. WebSocket stability and performance improvements include timeout handling for reads, improved buffer management during writes, synchronization fixes for inbound WebSockets, and asynchronous readiness checks that remove blocking sleeps. SSL context integration enhanced security by introducing NettySSLConnectionContext and extending NettyTCPConnectionContext to initialize and manage SSL contexts, settings, and protocols. These changes reduce blocking, increase throughput, and harden transport security, supporting more reliable API exposure and enterprise deployments.

Jan 1, 2024In 2024-01, OpenLiberty/open-liberty delivered two major Netty-based transport enhancements that improve reliability, security, and scalability of WebSocket and HTTP transport layers. WebSocket stability and performance improvements include timeout handling for reads, improved buffer management during writes, synchronization fixes for inbound WebSockets, and asynchronous readiness checks that remove blocking sleeps. SSL context integration enhanced security by introducing NettySSLConnectionContext and extending NettyTCPConnectionContext to initialize and manage SSL contexts, settings, and protocols. These changes reduce blocking, increase throughput, and harden transport security, supporting more reliable API exposure and enterprise deployments.
