Build Identifier: 

get type coercion error when using nativewindow with jit disabled

Reproducible: Always

Steps to Reproduce:

1. Download the 3.4.0.9271 (latest stable) version of the Flex SDK - decompress into c:\TestFlexSDK\

  http://opensource.adobe.com/wiki/display/flexsdk/Flex+SDK

2. Overlay C:\TestFlexSDK\ with the 20091002_withdrm AIR SDK

  \\vulcan\Apollo_1\Daily_Builds\athena\2.0\20091002_apams1041\win\results\Release\installers\archive_air_2.0_desktop_withdrm_sdk.zip

3. Using ADL in the SDK folder run the attached test application - which is a default AIR application that contains nothing but the default window.

  c:\TestFlexSDK\bin\adl JITTest-app.xml

  => The test application should launch.

4. Modify mms.cfg to disable the JIT.

  On Windows XP: C:\WINDOWS\system32\Macromed\Flash\mms.cfg

  AS3JIT = 0

5. Using ADL in the SDK folder run the attached test application - which is a default AIR application that contains nothing but the default window.

  c:\TestFlexSDK\bin\adl JITTest-app.xml

  => The test application will fail to launch with the following message:

  unknown error
  TypeError: Error #1034: Type Coercion failed: cannot convert flash.desktop::NativeApplication@3acb041 to flash.desktop.NativeApplication.
          at flash.desktop::NativeApplication$/get nativeApplication()
          at runtime::AppRunner$/GetLocalConnectionDomain()
          at runtime::AppRunner/run()
          at global/runtime::ADLEntry()

bug was reproduceable on windows xp and some version of mac os x (likely panther)

This turns out to NOT be a Tamarin bug -- the native classes in AIR are doing some type-spoofing internally, which happens to work in JIT mode (since the setslot calls don't do typechecking at runtime) but not in interpreter mode. Bounced the bug back to their internal bug database.
