In version 1.3~b8 that I have been packaging, Jack uses ASM 5.0.4 [1]. The upstream Jack is not affected by this particular problem because the source of Jack includes the source of all external dependencies which are compiled using Ant and javac and are included into `jack.jar` when Jack is being built. Thus, the classes of ASM are not shrunk and stay in Java 1.5.
You can see the commands compiling ASM in [2].
