In the upcoming #Java26, lazy constants get their second preview (JEP 526). java.lang.LazyConstant lets the app initialize them on demand with at-most-once semantics even under concurrency. Once initialized, the JVM can treat the value as a true constant and apply constant folding.👇

New on our channel: sizing JDBC connection pools for real production load. Many outages aren’t due to “slow DB”, it's pool exhaustion: ms queries, seconds waiting for a connection. @cat-edelveis.bsky.social covers sizing, timeouts, and when a proxy approach helps: youtu.be/0iHlROKQJcw

In the upcoming #Java26, the Vector API stays incubated for the 11th round (JEP 529). It lets you express SIMD-style loops with FloatVector/IntVector so HotSpot can reliably map them to AVX/NEON instructions at runtime, often beating scalar code.👇
