Hi,

We are having trouble deserializing rule packages on JBoss7 because JBoss7 / ModuleClassLoader 1.0.1.GA seem to ignore 
-Dsun.lang.ClassLoader.allowArraySyntax=true
ClassLoading was working properly on JBoss6 with -Dsun.lang.ClassLoader.allowArraySyntax=true
Is there any hidden option of ModuleClassLoader to reproduce native classloader behaviour and support class array syntax?

Here is stacktrace:
