I've tried again after extracting the archive with `tar`, since I was 
getting some warnings about symlinks while using `winrar`, and it seems 
that the extraction had failed.

Running again in cygwin I get:

     $ ./idealgraphvisualizer
     
/cygdrive/j/Projects/graalvm-ee-1.0.0-rc9/lib/visualizer/platform/lib/nbexec: 
WARNING: environment variable DISPLAY is not set
     
/cygdrive/j/Projects/graalvm-ee-1.0.0-rc9/lib/visualizer/platform/lib/nbexec: 
line 421: /cygdrive/j/Projects/graalvm-ee-1.0.0-rc9/bin/java: cannot 
execute binary file: Exec format error

It seems to be trying to use the bundled java executable, but I guess 
that is an ELF binary, so it can't run on Windows?

I also found an idealgraphvisualizer64.exe in the folder 
lib/visualizer/bin. I tried running this, but was getting a 'permission 
denied' error. I had to recursively reset the 'graalvm-ee-1.0.0-rc9' 
folder's permissions (I guess tar mucked them up).

When running again in PowerShell I get:

     Error occurred during initialization of boot layer
     java.lang.module.FindException: Module java.xml.bind not found

I'm using JDK 11 by default, which doesn't seem to have that module, but 
even after setting JAVA_HOME and PATH to JDK 10 (which does have the 
module) I'm still getting the same error. I'm not sure where it's 
picking up the JRE to use? It _does_ work if I move the jdk-11 folder 
from the default location, then it suddenly picks up my old installed 
JDK 8.

So I've gotten it to run and viewed some graphs with it as well :D I 
wonder why this executable is not bundled with the Windows GraalVM 
snapshot.

Cheers,
