Ok, I see. The initial implementation getGenericArrayType that should be simple is to handle primitive arrays. The problem is that the getGenericArrayType does not belong in the WeakTypeClass as a private method as it cannot be override to return an ArrayInfo. The implementation should simply be the following in IntrospectionTypeInfoFactoryImpl: | protected ArrayInfo getGenericArrayType(GenericArrayType type) | { | Type compType = type.getGenericComponentType(); | TypeInfo componentType = getTypeInfo(compType); | ArrayInfoImpl result = new ArrayInfoImpl(componentType); | return result; | } | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4113515#...
