[JDK-8153077] JNLP example with -XaddExports

[Reto Merz]

Hello,

Is there any documentation or a public available working example how to use 
-XaddExports for WebStart apps ?
I have no acces to the example mentioned in JDK-8153077.

We try this:
    <j2se version="1.8+" 
java-vm-args="-XaddExports:java.base/sun.security.action=ALL-UNNAMED"/>
  
and also this:
  <resources>
    <j2se version="1.8+"/>
    [..]
    <property name="addExports" 
value="java.base/sun.security.action=ALL-UNNAMED"/>
  </resources> 
  
In both cases WebStart throws a IAE. All our JARs are signed and JNLP also 
request all-permissions.
Tested with Java 9 b152 and Windows 7. Java Webstart Console output:
  
    Java Web Start 12.0.0.0
    Using JRE version 9-ea+152 Java HotSpot(TM) 64-Bit Server VM
    JRE expiration date: 11.07.17, 00:00
    User home directory = C:\Users\Administrator
    [..]
    #### Java Web Start Error:
    #### java.lang.IllegalAccessError: class ch.abacus.Java9Test (in unnamed 
module @0x4ab3b734) cannot access class sun.security.action.GetPropertyAction 
(in module java.base) because module java.base does not export 
sun.security.action to unnamed module @0x4ab3b734
    
Thanks
