Serializing a class that aggregates a map with variable type values fails.

[GoogleCodeExporter]

When I serialize a Map<String, IChild> where IChild can be of type ChildA or 
ChildB then Gson works correctly without a custom serializer.

When I aggregate this map into some other object "Root" and I serialize the 
Root object, then the map is no longer correctly serialized.

I included a JUnit4 test that exposes the problem...

This is an annoying bug since I wanted to use GSON to avoid needing to write 
too many unittests on the serialisation part of my code.

I don't need to deserialize the output that is done in the browser with GWT 
JavaScriptObject overlays.

Is anybody actually looking at issues in the team ?

I'll make sure this gets looked at before our 1.7 release. Have you been able 
to reproduce the problem on GSON 1.7 ?

I don't have aa 1.7 release, so I can not double check.
But this issue report contains a straightforward junit4 test, if it runs 
without error with the cirrent 1.7 then consider it fixed.

I tried my unittest with 1.7 and it fixes the bug.
Thanks for the fast release!

this bug is fixed, but I have the same issue with Lists.
