New features of Java 12 in action (live coding)
summary
Live coding in JShell live coding shows concrete Java 12 effects: switch expressions (preview) compiles and yields values but requires --enable-preview; compact number format is final but demos reveal locale formatting bugs; new Constable/ConstantDesc methods appear on String/Number but add API surface not new behavior; Shenandoah GC (experimental) is usable only on some OpenJDK builds while G1 gets mixed collections and abortable full collections; JDK Mission Control release is still delayed.
