Description

[All these steps assume you're using Flash Builder]

Steps to reproduce:
1. Create a new Flex project.
2. Create a new AS Class named "test"
3. In the AS Class, modify it to extend itself – i.e. test extends test
4. In the MXML App, create a script block with the following:

<fx:Script>
<![CDATA[
public function foo():void

{ new test(); }

]]
>
</fx:Script>

5. Save/Build.

Actual Results:
Flash Builder will popup a dialog about an uncaught exception in the compiler (see screen shots). Eclipse then encourages you to exit the workbench (basically you are forced to relaunch FB).

!ENTRY com.adobe.flexbuilder.project 4 43 2009-12-22 11:37:26.035
!MESSAGE Uncaught exception in compiler

at flex2.compiler.as3.binding.ClassInfo.getSkinParts(ClassInfo.java:143) etc...

Expected Results:
This exception should be handled gracefully within the compiler so that a user who types something like this accidentally doesn't get nasty error messages and have to reboot Flash Builder.

Workaround (if any):
