> I briefly tried to use java 9 for our tooling and to run servers.
> I downloaded it from here:
> https://jdk9.java.net/download/
> {code}
> nattura:8.0.2 rasp$ java -version
> java version "1.9.0-ea"
> Java(TM) SE Runtime Environment (build 1.9.0-ea-b45)
> Java HotSpot(TM) 64-Bit Server VM (build 1.9.0-ea-b45, mixed mode)
> {code}
> I use OS X 10.10 Yosemite.
> There are a couple of problems:
> 1. When I add a WildFly 8.2 server into JBDS 8.0.2, I cannot change the runtime to use java 9 - it seems we restrict that.
> 2. Even if I could, we need to make sure -XX:MaxPermSize is not used in the server launch command. When I tried to run WildFly 8.2 from the terminal, it wouldn't work unless I removed the max perm size argument. Apparently java 9 does not just ignore this parameter (as java 8 did), but it does not allow it at all.
> {code}
> nattura:bin rasp$ ./standalone.sh 
> =========================================================================
>   JBoss Bootstrap Environment
>   JBOSS_HOME: /Users/rasp/jbossqa/runtimes/wildfly-8.2.0.Final
>   JAVA: /Library/Java/JavaVirtualMachines/jdk1.9.0.jdk/Contents/Home/bin/java
>   JAVA_OPTS:  -server -Xms64m -Xmx512m -XX:MaxPermSize=256m -Djava.net.preferIPv4Stack=true -Djboss.modules.system.pkgs=org.jboss.byteman -Djava.awt.headless=true
> =========================================================================
> Unrecognized VM option 'MaxPermSize=256m'
> Error: Could not create the Java Virtual Machine.
> Error: A fatal exception has occurred. Program will exit.
> {code}
> Of course it's questionable if we should allow java 9 for current servers at all as they don't support it officially. But I would say there is no need to restrict it if it works.
