While processing a version of `cardview-v7.jar`, `class-parse --dump` was throwing a `NullReferenceException`: $ mkdir cardview-v7 $ cd cardview-v7 $ unzip ../cardview-v7.jar $ mono …/class-parse.exe -v --dump android/support/v7/widget/CardView.class >/dev/null class-parse: Unable to read file 'android/support/v7/widget/CardView.class': System.NullReferenceException: Object reference not set to an instance of an object at Xamarin.Android.Tools.Bytecode.InnerClassInfo.ToString () ... The `NullReferenceException` is because one of the `InnerClassInfo` values which `InnerClassInfo.ToString()` references is `null`. After fixing, we see: Attributes Count: 2 0: Unknown[SourceFile](2) 1: InnerClasses(Count=7, InnerClass(InnerClass='android/support/v7/widget/CardView$1', OuterClass='', InnerName='', InnerClassAccessFlags=0), InnerClass(InnerClass='android/R$attr', OuterClass='android/R', InnerName='attr', InnerClassAccessFlags=Public, Static, Final), InnerClass(InnerClass='android/view/View$MeasureSpec', OuterClass='android/view/View', InnerName='MeasureSpec', InnerClassAccessFlags=Public, Static), InnerClass(InnerClass='android/support/v7/cardview/R$styleable', OuterClass='android/support/v7/cardview/R', InnerName='styleable', InnerClassAccessFlags=Public, Static, Final), InnerClass(InnerClass='android/support/v7/cardview/R$style', OuterClass='android/support/v7/cardview/R', InnerName='style', InnerClassAccessFlags=Public, Static, Final), InnerClass(InnerClass='android/support/v7/cardview/R$color', OuterClass='android/support/v7/cardview/R', InnerName='color', InnerClassAccessFlags=Public, Static, Final), InnerClass(InnerClass='android/os/Build$VERSION', OuterClass='android/os/Build', InnerName='VERSION', InnerClassAccessFlags=Public, Static)) I'm not sure why `CardView$1` has no `InnerClassInfo.OuterClass` value -- shouldn't it be `android/support/v7/widget/CardView`? -- but that doesn't really matter; `class-parse --dump` shouldn't fail here.
