5849     * the responsibility to ensure that the static assumptions on classes in the optimized code
5850     * hold at runtime (e.g. there's no duplicate classes in the classpath).

5853     * {@link dalvik.system.DexClassLoader} and {@link dalvik.system.PathClassLoader}.

5857     * the given callback.
5858     *
5859     * If the module is intended to be shared with other apps, make sure that the file
5860     * permissions allow for it.
5861     * If at registration time the permissions allow for others to read it, the module would
5862     * be marked as a shared module which might undergo a different optimization strategy.
5863     * (usually shared modules will generated larger optimizations artifacts,
5864     * taking more disk space).
