JEP-295 AOT compilation issue with JDK 10

[Vladimir Kozlov]

Thank you for trying AOT!

I ran the same command with JDK10 I build myself on Linux-x64 (Oracle's 
distro) from latest jdk10 sources and it passed.

I also downloaded official JDK10 from 
http://www.oracle.com/technetwork/java/javase/downloads/jdk10-downloads-4416644.html

$ java -version
java version "10" 2018-03-20
Java(TM) SE Runtime Environment 18.3 (build 10+46)
Java HotSpot(TM) 64-Bit Server VM 18.3 (build 10+46, mixed mode)

And it passed too.

Something is wrong with JDK you are using (damaged?):

*Caused by: java.lang.ClassFormatError: Incompatible magic value 0 in 
class file jdk/nio/zipfs/ZipFileSystemProvider*

If you still want to try you can exclude this class from compilation - 
add next line to your java.base-list.txt file:

exclude jdk.nio.zipfs.ZipFileSystemProvider.*

Regards,
Vladimir
