Hi,

desugaring the JarFileEntry::new in JarFile::getEntry0 avoids a hefty 
startup regression on our smallest startup tests:

http://cr.openjdk.java.net/~redestad/8193064/open.00/

I think the implementation could be improved further by using static 
non-capturing functions rather than Jar-/ZipFileEntry::new (which, since 
they reference a non static class constructor, are implicitly capturing) 
and filed: https://bugs.openjdk.java.net/browse/JDK-8193066

Thanks!
