Well there's your problem! Your engine's missing! A look under Java's hood
summary
Walks through real class files and shows exact bytecode patterns produced by javap, ASM and an IDE analyze byte code plugin plus a jbang build script — getters/setters use aload/putfield, loops compile to compare-and-jump sequences, switches become jump tables, and new switch expressions still emit the same bytecode. Highlights: generics mostly erase to Object with a synthetic bridge method, lambdas use invokeDynamic and cause a constant pool explosion, and nestmates replace compiler-generated accessors.
