commit 21c793d886df49dfc8302c5506f8c673ba1d47c0 Author: 虎鸣 <[email protected]> AuthorDate: Sun Jun 14 18:25:49 2026 +0800 feat: Add -Yfuture-lazy-vals for Scala 3.3.x builds Motivation: The Scala 3.3.8 compiler introduced the -Yfuture-lazy-vals flag to optionally use VarHandle instead of sun.misc.Unsafe for lazy val implementation. This prepares libraries for upcoming JDK releases that restrict sun.misc.Unsafe access. Modification: Add -Yfuture-lazy-vals to scalacOptions, conditionally applied only for Scala 3.3.x via CrossVersion.partialVersion or scalaBinaryVersion. Result: Scala 3.3.x build uses the future-proof VarHandle-based lazy val implementation, compatible with all JDK 9+ versions including future releases that restrict sun.misc.Unsafe.
