RFR [9] 8139706: JarFile.getBytes could use InputStream.readNBytes

[Claes Redestad]

Hi Bernd,

thanks for looking at this!

You're right about the semantic change for this patch in isolation, but 
compared to the previous implementation that used sun.misc.IOUtils the 
semantics are unchanged (compare with theprevious implementation of 
JarFiles::getBytes and sun.misc.IOUtils::readFully in 
http://hg.openjdk.java.net/jdk9/dev/jdk/rev/5537b74dea17 )
