Fixing Hessian Flex 3.2.0 References

If you're using Hessian Flex 3.2.0 and you'd like to fix the problem with references, the following one-line fix seems to do the job for me:

$ svn diff
Index: src/main/flex/hessian/io/Hessian2Input.as
===================================================================
--- src/main/flex/hessian/io/Hessian2Input.as (revision 1172)
+++ src/main/flex/hessian/io/Hessian2Input.as (working copy)

     public override function init(di:IDataInput):void
     {
       _di = di;
       _buffer = new ByteArray();
       _offset = 0;
       _length = 0;
+      _refs = null;
     }

Basically, HessianOperation hangs on to a Hessian2Input class between invocations, and calls init() to clear out the state before using the class for another invocation. The init() doesn't currently clear the reference cache. By setting _refs to null, you clear the cache and Hessian2Input will simply instantiate a new array in its place if and when it needs to do so.
