New description:

 [wiki:Vector] appears to have its own, undocumented AMF3 data type, code
 `0x0D`.  The attached files demonstrate the problem:

  - vector_test.mxml - Flex 4 source file with Vector of Strings
  - vector_test.swf - Flash Player SWF that echoes Vector of strings to
 localhost:8000
  - AMF3_Vector.hx - haXe source example
  - AMF3_Vector.swf - Flash file that produces the unsupported code.
  - AMF3_Vector.sol - Final .sol output, as produced by Flash v10.0.32.18
 (Linux).

 == AMF3 Vector with Java ==

 Red5 implemented and [http://blog.infrared5.com/2011/08/red5-vector-
 support/ documented this]. Also check this [http://code.google.com/p

 class] and [http://jpauclair.net/2010/01/16/reverse-engineering-amf3
