Hi Jason/Tomaz, Early Access b118 <https://jdk9.java.net/download/> for JDK 9 is available on java.net, summary of changes are listed here <http://www.java.net/download/java/jdk9/changes/jdk-9+118.html>;. Early Access b118 <https://jdk9.java.net/jigsaw/> (#4913) for JDK 9 with Project Jigsaw is available on java.net. JDK 9 Build 118 includes a refresh of the module system. There are several changes in this update, JDK 9 b118 has the updated policy for root modules described in JEP 261 [1]. This means that java.corba and the 6 EE modules aren't resolved by default and so it will look "as if" the types in these modules have been removed. More info on the JDK 9 dev mailing list [2]. A change that went into JDK 9 b102 is worth mentioning: JDK9: Remove stopThread RuntimePermission from the default java.policy In previous releases, untrusted code had the "stopThread" RuntimePermission granted by default. This permission allows untrusted code to call Thread.stop(), initiating an asynchronous ThreadDeath Error, on threads in the same thread group. Having a ThreadDeath Error thrown asynchronously is not something that trusted code should be expected to handle gracefully. The permission is no longer granted by default.
