Hi,

does this actually means that this feature in now "out of the box" and the system property 
-Dsun.lang.ClassLoader.allowArraySyntax=true doesnt have to be set anymore? 
I'm currently having the following problem while using JBoss 7.1.0.Final: 
* I set the -Dsun.lang.ClassLoader.allowArraySyntax=true propery and can see that it is passed to the JVM at boot
