Description
While trying to get X-Pack yaml tests running in a 3 node cluster (usually they run in a single node cluster) I noticed a problem with serialization between nodes for geo shapes. The problem is that the search hit serialization code expects to be able to serialize the hit contents as “generic values” but there’s no generic value writer that works for geo shapes. The effect is to crash a node in the cluster:
java.lang.IllegalArgumentException: can not write type [class org.elasticsearch.xpack.spatial.index.fielddata.GeoShapeValues$GeoShapeValue]

This indicates a bug in the transport layer I think (although only as a consequence of other bugs): it’s not safe to bubble an exception up all the way from OutboundHandler.sendResponse to the ChannelActionListener like this, because of the double-free problem that this AssertionError highlights. We need to handle the exception in the OutboundHandler somehow.
