A 2%-4% regression was measured with footprint3-server in JDK9-b86 on all platforms.

~~JDK-8138978~~ removed sun.misc.IOUtils and left JarFile.getBytes using InputStream.readAllBytes, which is sub-optimal when the ZipEntry size is known.

Using readNBytes might improve startup and early footprint characteristics.
