Description

—

It looks like combination of polymorphic types (@JsonTypeInfo) and managed references does not work completely; serialization does not seem to include proper type information in serialized JSON.

Ah. Actually took bit longer to get to actual reported issue; code was assuming bean or container serializer, but must also accept AbstractDeserializer.

Hmmh. Also, rather non-trivial to fix: problem is that AbstractDeserializer is pretty much a placeholder, having little information ans specifically has no properties.
But maybe we'll get more ideas over time, so leaving this open.

Note: there is a unit test: org.codehaus.jackson.map.deser.TestParentChildReferences#testAbstract to reproduce this problem.
