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/
--- src/main/flex/hessian/io/ (revision 1172)
+++ src/main/flex/hessian/io/ (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.
