[flexcoders] Subclassing "Class": The ABC data is corrupt.

[verifyfailed]

Is subclassing "Class" legal?

I have code like this:

<pre>
public class ArrayOf extends Class {
  public var elementType : Class;
                
  public function ArrayOf(elementType : Class) {
    this.elementType = elementType;
  }
}
</pre>

Which compiles just fine, but when I run it, I get a bytecode
verification error, like so:

<pre>
verify global$init()
                        stack:
                        scope:

Any Tamarin experts out there?
